he profit earned by a hot dog stand is a linear function of the number of hot dogs sold. It costs the owner $48 dollars each morning for the day’s supply of hot dogs, buns and mustard, but he earns $2 profit for each hot dog sold. Which equation represents y, the profit earned by the hot dog stand for x hot dogs sold?
y=48x−2
y=48x+2
y=2x−48
y=2x+48
The linear function that represents the profit earned is: C. y = 2x − 48.
How to Write a Linear Function?The linear Function can be written as y = mx + b, which is in slope-intercept form, where we have:
x and y as the variables.m as the slope/unit rate.b as the starting value or y-intercept of the linear function.From the information given, we have:
x = number of hot dogs sold
y = Profit earned
m = unit rate = 2
b = starting value = -48 (this is negative because the profit on each hot dog sold must be deducted from the cost for each morning.)
Therefore, substitute m = 2 and b = -48 into y = mx + b to write the linear function:
y = 2x - 48

Determine the bonus based upon the formula 2 weeks' salary plus 1 percent commission:
annual salary: $48,000.00
yearly sales: $76,000.00
The bonus based upon the given formula is $2606.15 approximately
Given,
Annual salary = $48,000
Yearly sales = $76,000
Bonus is given according to the formula:
2 weeks salary + 1 percentage commission
Here,
Annual salary is given as $48,000
We have to find the weekly salary:
There is 52 weeks in a year.
So, salary for one week = Annual salary / number of weeks = 48000/52 = $923.077
Now, salary for two weeks = 923.077 × 2 = $1846.154
Rate of annual commission is 1%
The commission amount:
1% of yearly sales = 1% of 76000 = (1/100) × 76000 = $760
So,
The bonus amount = 2 weeks salary + 1 percentage commission
The bonus amount = 1846.154 + 760
The bonus amount = 2606.154
Therefore, the bonus given based upon the given formula is $2606.154

2 regular pizzas and 3 small pizzas cost £43 8 regular pizzas and 9 small pizzas cost £151 find the cost of one of each
Taking into account the definition of a system of linear equations, a small pizza and a regular pizza cost £7 and £11 respectively.
System of linear equationsA system of linear equations is a set of two or more equations of the first degree, in which two or more unknowns are related.
Solving a system of equations consists of finding the value of each unknown so that all the equations of the system are satisfied. This mieans thar systems of linear equations have as a solution set all ordered pairs (x, y) that satisfy the equation, where x and y are real numbers.
This caseIn this case, a system of linear equations must be proposed taking into account that:
"r" is the cost of a regular pizza."s" is the cost of a small pizza.You know:
2 regular pizzas and 3 small pizzas cost £43.8 regular pizzas and 9 small pizzas cost £151.The system of equations to be solved is
2r + 3s= 43
8r + 9s= 151
Of the several methods to solve a system of equations. it is decided to solve it using the substitution method, which consists of clearing one of the two variables in one of the equations of the system and substituting its value in the other equation.
In this case, isolating the variable "r" from the first equation:
2r= 43 - 3s
r= (43 -3s)÷2
r= 43/2 - 3/2s
Replacing this expression in the second equation:
8×(43/2 - 3/2s) + 9s= 151
Solving:
8×43/2 - 8×3/2s + 9s= 151
172 -12s + 9s= 151
-12s + 9s= 151 - 172
-3s= -21
s= (-21)÷ (-3)
s= 7
Remembering that r=43/2 - 3/2s you get:
r=43/2 - 3/2×7
r= 11
Finally, a small pizza cost £7 and a regular pizza cost £11.

Tony went on holiday to Canada.
His flights cost a total of £1600
Tony stayed for 12 nights.
His hotel cost $184 per night.
Tony used wifi for 9 days.
Wifi cost $6 per day.
Tony took a taxi 6 times costing a mean average of $27 per taxi journey.
The exchange rate was $1.83 to £1
Work out the total cost of the flights, the hotel room, the wifi and 6 taxi journeys.
Give your answer in pounds.
Answer:
Step-by-step explanation:
(12 nights)($184) = $2208
(9 nights)($6) = $54
(6 taxi rides)($27) = $162
$2208 + $54 + $162 = $2424
We will use a ratio to calculate American dollars to pounds
2424/x = 1.83/1
Cross multiply
1.83x=2424
Divide
= ~£1324.59
£1324.59 + £1600 = £2924.59
The answer is ~2924.59 pounds
The total cost of the flights, the hotel room, the wifi, and 6 taxi journeys for Tony's holiday in Canada is approximately £2925.13.
Given that Tony is vacationing in Canada, his flight cost is £1600, he stayed for 12 nights, his hotel cost $184 per night, Tony used wifi for 9 days. Wifi cost $6 per day. Tony took a taxi 6 times costing a mean average of $27 per taxi journey.
The exchange rate was $1.83 to £1.
We need to find the total cost his spend in the vacation.
To calculate the total cost of Tony's holiday, we need to convert all the expenses to pounds and then sum them up.
Flights cost: £1600
Hotel cost per night: $184
Hotel cost for 12 nights: 12 nights x $184/night = $2208
Wifi cost per day: $6
Wifi cost for 9 days: 9 days x $6/day = $54
Taxi cost per journey (mean average): $27
Total taxi cost for 6 journeys: 6 journeys x $27/journey = $162
Now, we need to convert the costs from dollars to pounds using the exchange rate of $1.83 to £1.
Flights cost in pounds: £1600
Hotel cost in pounds: $2208 / $1.83 = £1207.10
Wifi cost in pounds: $54 / $1.83 = £29.51
Taxi cost in pounds: $162 / $1.83 = £88.52
Finally, we can calculate the total cost in pounds:
Total cost = Flights cost + Hotel cost + Wifi cost + Taxi cost
Total cost = £1600 + £1207.10 + £29.51 + £88.52
Total cost = £2925.13
So, the total cost for Tony's holiday in Canada is approximately £2925.13.

What are corresponding angles?
Two lines are parallel if and only if the two angles of any pair of transversal corresponding angles are congruent (equal in measure). Proposition 1.28 of Euclid's Elements, an absolute geometry theorem (therefore true in both hyperbolic and Euclidean Geometry), demonstrates that if the angles of two transversals are corresponding, the two lines are parallel (non-intersecting). According to Euclid's parallel postulate, if two lines are parallel, the angles of a pair of corresponding angles are congruent (Proposition 1.29 of Euclid's Elements). If the angles of one pair of related angles are congruent, the angles of the remaining pairs are likewise congruent.

X
Answer: C
f(x)= x^4(x-a)(x-b)^2
Answer:
[tex]f(x)=x^4(x-a)(x-b)^2[/tex]
Step-by-step explanation:
The graph of a polynomial function will:
touch the x-axis at zeros with even multiplicities. cross the x-axis at zeros with odd multiplicities.The zero at the origin (0, 0) touches the x-axis and so it has an even multiplicity (exponent). Therefore, we can immediately discount the first two answer options as both have x as a zero (x = x¹ so its exponent is odd).
The end behavior of the graphed function means the leading coefficient is positive and the degree of the polynomial is odd.
The sum of the multiplicities is the degree of the polynomial function.
[tex]f(x)=x^4(x-a)(x-b)^2 \implies \textsf{Sum of multiplicities}: 4+1+2=7[/tex]
[tex]f(x)=x^2(x-a)^5(x-b) \implies \textsf{Sum of multiplicities}: 2+5+1=8[/tex]
Therefore, the only function that could represent the given graph is

as its degree is odd and it has a zero at the origin with even multiplicity.

The school mary goes to is selling tickets to a fall musical. On the first day of ticket sales the school sold 7 senior citizen tickets and 6 students tickets of $69. The school took in $53 on the second day by selling 7 senior citizen tickets and 4 student tickets. find the price of one senior citizen ticket an the price of one child ticket
The price of one senior citizen ticket is $8 and that of a child ticket is $3.
Let the price of one senior citizen ticket be x
and the price of one student ticket be y
Thus, for the first day, we can make the following equation-
7x + 6y = 69
and similarly, we can make an equation for the second day as-
7x + 4y = 53
Now, we can solve these two linear equations to find the value of x and y.
Subtracting equation 2 from 1 we get-
(7x + 6y) - (7x + 4y) = 69 - 53
7x - 7x + 6y - 4y = 16
6y - 4y = 16
2y = 16
y = 16/2
y = 8
Substituting the value of y in any of the two equations we can find the value of x-
7x + 6(8) = 69
7x = 69 - 48
x = 21/7
x = 3
Thus, the price of one senior citizen ticket is $8 and that of a child ticket is $3.

x2-6=54, first you have to cancel out the 6 on the left side by adding 6 to -6 after doing that you are left with
x2-(-6+6)=54

The features of the triangle are summarized below:
AC = √7 + √6 AB² = AC² = 13 + 2√42, BC² = 13 + 2√42.There is 45-45-90 right triangle as BC = √2 · AB = √2 · AC. The triangle has an area of approximately 12.980 square units.How to analyze a given triangle based on its sides
In this problem we find the case of a triangle whose three sides (AB, AC, BC) are known. First, we rationalize the expression for AC, that is, eliminate the irrational denominator by algebraic means:
AC = 1 / (√7 - √6)
AC = [1 / (√7 - √6)] · [(√7 + √6) / (√7 + √6)]
AC = (√7 + √6) / [(√7 - √6) · (√7 + √6)]
AC = (√7 + √6) / (7 - 6)
AC = √7 + √6
Second, we determine the square of each side:
AB² = (√7 + √6)²
AB² = 7 + 2√42 + 6
AB² = 13 + 2√42
AC² = (√7 + √6)
AC² = 13 + 2√42
BC² = (√14 + 2√3)²
BC² = 14 + 4√42 + 12
BC² = 26 + 4√42
BC² = 2 · (13 + 2√42)
BC² = 2 · AB² = 2 · AC²
Third, deduce the nature of the triangle:
Since BC = √2 · AB = √2 · AC, then the triangle ABC is a right triangle with internal angles 45° - 45° - 90°.
Fourth, calculate the area of the triangle by Heron's formula:
s = 0.5 · (AB + AC + BC)
s = 0.5 · (√7 + √6 + √7 + √6 + √14 + 2√3)
s = 0.5 · (2√7 + 2√6 + √14 + 2√3)
s = √7 + √6 + 0.5√14 + √3
A = √[s · (s - AB) · (s - AC) · (s - BC)]
A = √[(√7 + √6 + 0.5√14 + √3) · (√7 + √6 + 0.5√14 + √3 - √7 - √6) · (√7 + √6 + 0.5√14 + √3 - √7 - √6) · (√7 + √6 + 0.5√14 + √3 - √14 - 2√3)]
A = √[(√7 + √6 + 0.5√14 + √3) · (0.5√14 + √3) · (0.5√14 + √3) · (√7 + √6 - 0.5√14 - √3)]
A = √[8.698 · (8.698 - 5.095) · (8.698 - 5.095) · (8.698 - 7.206)]

x = sqrt((-2 i) y + 1/4) + 1/2 (-2 i y + 1) or x = 1/2 (-2 i y + 1) - sqrt(((-2 i) y + 1/4))
Step-by-step explanation:
Solve for y:
(x + (0 + i) y)^2 = x + (0 - i) y
Subtract -i y + x from both sides:
-x + (i y + x)^2 + i y = 0
Expand and collect in terms of y:
-x + x^2 + y (2 i x + i) - y^2 = 0
Multiply both sides by -1:
x - x^2 + y (-2 i x - i) + y^2 = 0
Subtract -x^2 + x from both sides:
y (-2 i x - i) + y^2 = x^2 - x
Add 1/4 (-2 i x - i)^2 to both sides:
1/4 (-2 i x - i)^2 + y (-2 i x - i) + y^2 = 1/4 (-2 i x - i)^2 - x + x^2
Write the left hand side as a square:
(1/2 (-2 i x - i) + y)^2 = 1/4 (-2 i x - i)^2 - x + x^2
Take the square root of both sides:
1/2 (-2 i x - i) + y = sqrt(1/4 (-2 i x - i)^2 - x + x^2) or 1/2 (-2 i x - i) + y = -sqrt(1/4 (-2 i x - i)^2 - x + x^2)
Subtract 1/2 (-2 i x - i) from both sides:
y = 1/2 (2 i x + i) + sqrt((((-2 i) x - i)^2)/4 - x + x^2) or 1/2 (-2 i x - i) + y = -sqrt(1/4 (-2 i x - i)^2 - x + x^2)
1/4 (-2 i x - i)^2 - x + x^2 = -2 x - 1/4:
y = 1/2 (2 i x + i) + sqrt((-2 x - 1/4)) or 1/2 (-2 i x - i) + y = -sqrt(1/4 (-2 i x - i)^2 - x + x^2)
Subtract 1/2 (-2 i x - i) from both sides:
y = sqrt(-2 x - 1/4) + 1/2 (2 i x + i) or y = 1/2 (2 i x + i) - sqrt((((-2 i) x - i)^2)/4 - x + x^2)
1/4 (-2 i x - i)^2 - x + x^2 = -2 x - 1/4:
Answer: y = sqrt(-2 x - 1/4) + 1/2 (2 i x + i) or y = 1/2 (2 i x + i) - sqrt((-2 x - 1/4))

Solve for x:
(x + (0 + i) y)^2 = x + (0 - i) y
Subtract -i y + x from both sides:
-x + (i y + x)^2 + i y = 0
Expand and collect in terms of x:
x^2 + x (2 i y - 1) + i y - y^2 = 0
Subtract -y^2 + i y from both sides:
x^2 + x (2 i y - 1) = y^2 - i y
Add 1/4 (2 i y - 1)^2 to both sides:
x^2 + x (2 i y - 1) + 1/4 (2 i y - 1)^2 = 1/4 (2 i y - 1)^2 - i y + y^2
Write the left hand side as a square:
(x + 1/2 (2 i y - 1))^2 = 1/4 (2 i y - 1)^2 - i y + y^2
Take the square root of both sides:
x + 1/2 (2 i y - 1) = sqrt(1/4 (2 i y - 1)^2 - i y + y^2) or x + 1/2 (2 i y - 1) = -sqrt(1/4 (2 i y - 1)^2 - i y + y^2)
Subtract 1/2 (2 i y - 1) from both sides:
x = 1/2 (-2 i y + 1) + sqrt((((2 i) y - 1)^2)/4 - i y + y^2) or x + 1/2 (2 i y - 1) = -sqrt(1/4 (2 i y - 1)^2 - i y + y^2)
1/4 (2 i y - 1)^2 - i y + y^2 = -2 i y + 1/4:
x = 1/2 (-2 i y + 1) + sqrt(((-2 i) y + 1/4)) or x + 1/2 (2 i y - 1) = -sqrt(1/4 (2 i y - 1)^2 - i y + y^2)
Subtract 1/2 (2 i y - 1) from both sides:
x = sqrt((-2 i) y + 1/4) + 1/2 (-2 i y + 1) or x = 1/2 (-2 i y + 1) - sqrt(((2 i y - 1)^2)/4 - i y + y^2)
1/4 (2 i y - 1)^2 - i y + y^2 = -2 i y + 1/4:
Answer: x = sqrt((-2 i) y + 1/4) + 1/2 (-2 i y + 1) or x = 1/2 (-2 i y + 1) - sqrt(((-2 i) y + 1/4))

How do you Make Seven an even number?
Just take off the "S" from Seven.
"Even" is formed.
How to make Seven an even number?Just take the "S" out of Seven. It becomes "even."
An even number is one that divides by two and leaves a 0 as the final result.
2, 4, 6, 8, 10, and other even numbers are examples.
To really make 7 an even number, add 1.
7 + 1 = 8
It becomes 8, which is even.
Another way to make it even is to subtract 1.
7 - 1 = 6
It becomes 6, which is even.
