Answer:
x + y ≥ 26 + 15
5x + 8y ≥ 250 (see below)
Step-by-step explanation:
First, write an equation to represent the total cost to wash cars:
$5x = cost for cars
Then, write another for trucks:
$8y = cost for trucks
If the question is saying that they will wash at least 26 cars and 15 trucks, that means they could wash more. This means that we'll need an inequality:
This inequality represents that the total number of cars and trucks they wash will be at least—which means that it is equal to or greater than—than the amount given:
x + y ≥ 26 + 15
Any equation or inequality with two unknowns is not solvable, meaning we need a system of equations:
If they make at least $250, that means that we need to combine the costs of the cars and trucks to make an inequality:
5x + 8y ≥ 250
Now you have your system of equations:
x + y ≥ 26 + 15
5x + 8y ≥ 250

Step-by-step explanation:
Sharon owns a car lot in Virginia Beach. For every car that parks in her parking lot, she charges $5.00 per day. She uses this equation to determine her daily income: y = 5x, where x is the number of cars and y is the amount of money earned. What is true about this function?
Answer and Step-by-step explanation:
Given the function y = 5x where x is the total number of cars parked in her lot and y is the total money earned. Since x is the independent variable as the money earned, y, depends on the amount of cars parked, we can say that the domain (the actual values the independent variable can assume) of this function is:
x = {0, 1, 2, 3, . . .}
This is because x, the number of cars, can never be a negative number..
Also, the range, the set of all the values of the dependent variable y, is: {all the numbers divisible by 5, including 0}
as shown, several parallelograms are formed in an expandable gate. The angles of the parallelograms change as the gate is expanded and compressed. Find m
Answer:
m = 145
Step-by-step explanation:
All angles inside a parallelogram = 360
∠ABC = ∠ADC
35 = ∠ADC
360 = 2(∠ABC) + 2( ∠DAB)
360 = 70 + 2( ∠DAB)
290 = 2( ∠DAB)
145 = ∠DAB
The adjacent angle of the parallelogram are supplementary angles. If the angle ∠ABC is 35°. Then the angle ∠DAB will be 145°.
What is a parallelogram?It is a polygon with four sides. The total interior angle is 360 degrees. A parallelogram's opposite sides and angles are parallel and equal.
In the parallelogram ABCD, the angle ∠ABC is 35°.
We know that adjacent angle of the parallelogram are supplementary angles.
∠ABC + ∠DAB = 180°
35° + ∠DAB = 180°
∠DAB = 180° – 35°
∠DAB = 145°

On a coordinate plane, a line goes through (negative 8, 4) and (8, 4). A point is at (negative 4, negative 6).
What is the equation of the line that is parallel to the given line and passes through the point (−4,−6 )?
x = −6
x = −4
y = −6
y = −4
Answer:
The equation of parallel line passes through the point (−4,−6 ) is:
y = -6
Please also check the attached graph.
Step-by-step explanation:
The slope-intercept form of the line equation
y = mx+b
where
m is the slopeb is the y-interceptGiven that on a coordinate plane passes through (-8, 4) and (8, 4).
As the value of y remains the same for any value of x.
i.e. y = 4 for any value of x.
Thus, the given line is a horizontal line.
We know that the slope of a horizontal line is zero.
Also it is clear that at x = 0, the value of y = 4. In other words, we can observe that the y-intercept b = 4.
so substitutig m = 0 and b = 4 in the slope-intercept form
y = mx + b
y = 0x + 4
y = 4
Therefore, the equation of line passing through the point (-8, 4) and (8, 4) is:
y = 4
Now, we also know that the slope of parallel lines is equal.
Thus, the slope of the line parallel to the line y = 4 is also 0.
As the parallel line passes through (−4,−6 ).
so substituting m = 0 and (-4, -6) in the slope-intercept form of line equation to determine the y-intercept b
y = mx + b
(-6) = 0(-4) + b
-6 = 0 + b
switching the sides
0 + b = -6
b = -6
Thus, the slope-intercept b = -6
now substituting m = 0 and b = -6 in the slope-intercept form of line equation
y = mx + b
y = 0(x) + -6
y = 0 - 6
y = -6
Therefore, the equation of parallel line passes through the point (−4,−6 ) is:
y = -6

How can you isolate the variable in this equation? x + 6 = 13
You can isolate the variable by subtracting 6 from both sides.
e.g.
x + 6 = 13
- 6 - 6
Now we have x = 7, which not only isolates the variable but solves for x.
If you don't know why we can subtract from both sides, look up the Addition Property of Equality and Subtraction Property of Equality.

The Student Advisory Council here at PC sells red and pink carnations every year for Valentine's Day. The number of red carnations sold was 3 more than 2 times the number of pink carnations sold. Red Carnations were sold for $ 0.50 each and Pink Carnations sold for $0.75 exh . The club made $600.00 . How many of each carnation were sold?
Answer:
The number of :
Red carnations sold = x = 687 carnations
Pink carnations sold = y = 342 carnations
How many of each carnation were
Step-by-step explanation:
Let us represent
The number of :
Red carnations = x
Pink carnations = y
The Student Advisory Council here at PC sells red and pink carnations every year for Valentine's Day.
The number of red carnations sold was 3 more than 2 times the number of pink carnations sold.
x = 3 + 2y .....Equation 1
Red Carnations were sold for $ 0.50 each and Pink Carnations sold for $0.75 exh . The club made $600.00 .
$0.50 × x + 0.75 × y = $600
0.5x + 0.75y = 600...... Equation 2
Using substitution method:
Let us substitute, 3 + 2y for x in Equation 2
0.5(3 + 2y) + 0.75y = 600
1.5 + y + 0.75y = 600
y + 0.75y = 600 - 1.5
1.75y = 598.5
y = 598.5/ 1.75
y = 342 carnations.
Solving for x
x = 3 + 2y .....Equation 1
x = 3 + 2(342)
x = 3 + 684
x = 687 carnations
Therefore, The number of :
Red carnations = x = 687 carnations
Pink carnations = y = 342 carnations

Problem 3
repeat steps

x=- 2/3
to find the y's, go back and plug in
Prob 1: y=(3+4) =7
Prob 2: y=[3(10)+5] =35
Prob 3: y=(-2/3) =-2/3
Answer:
1.)
y = 2x + 1
y = x + 4
Substitute
2x + 1 = x + 4
Subtract 1 on both sides
2x + 1 - 1 = x + 4 - 1
2x = x + 3
Subtract x on both sides
2x - x = x - x + 3
x = 3
Now that we have x we can use that for finding y
y = x + 4
y = 3 + 4
y = 7
x = 3
y = 4
( 3, 4 )
__________________________________________________________
2.)
y = 4x - 5
y = 3x + 5
Substitute
4x - 5 = 3x + 5
Add 5 on both sides
4x - 5 + 5 = 3x + 5 + 5
4x = 3x + 10
Subtract 3x on both sides
4x - 3x = 3x - 3x + 10
x = 10
Now that we have x, we can use that to find y
y = 3x + 5
y = 3 (10) + 5
y = 30 + 5
y = 35
x = 10
y = 35
( 10, 35)
__________________________________________________________
3.)
y = x
y = 4x + 2
Substitute
x = 4x + 2
Subtract 4x on both sides
x - 4x = 4x - 4x + 2
-3x = 2
Divide -3 on both sides to isolate the variable
-3x/-3 = 2/-3
x = -2/3
Now that we have that we can use it to find y
y = x
y = -2/3
x = -2/3
y = -2/3
( -2/3, -2/3)

A hot air balloon is descending at a rate of 287 feet per minute.
Find the total change in elevation of the balloon in 4 minutes.
Answer:
Please check the explanation.
Step-by-step explanation:
The slope-intercept form of the line equation
[tex]y = mx+b[/tex]
where
m is the rate of change or slopeb is the y-interceptA hot air balloon is descending at a rate of 287 feet per minute.
Thus, the rate of change m = -287
The negative sign indicates that a hot air balloon is descending.
Let y be elevation.
Let x be the time (in minutes)
As there is no mentioning of the initial height.
Thus, the y-intercept b = 0
now substituting m = -287 and b = 0
y = mx + b
y = -287x + 0
y = -287x
In order to determine the total change in elevation of the balloon in 4 minutes, we need to substitute x = 4 in the equation y = -287x.
Thus, the total change in elevation of the balloon in 4 minutes will be:
y = -287x
y = -287(4)
y = -1148 feet
The negative sign indicates that that the elevation is decreasing.

A person Rents a canoe for 4 Hours and paid a total of $36. of Renting a canoe costs am initial fee of the $2 Plus an additional amount for each hour the canoe is rented,which graph represents the total cost,y, in dollars of renting a canoe for x hours
Answer:
Additional fee or hour = $8.5
y = $2 + 8.5x
Step-by-step explanation:
Given that :
Total paid = $36
Number of hours = 4
Initial rental fee = $2
Additional fee per hour = a
Total amount = initial rental fee + additional fee per hour * number of hours
36 = 2 + 4a
36 - 2 = 4a
34 = 4a
a = 8.5
Hourly fee = $8.5
Therefore, the cost formula
y = initial fee + regular fee * number of hours
y = $2 + 8.5x
