In exercises 8-10, write a system of linear equations that has the ordered pair as its solution. (-6, -2)
Answer:
(8) [tex]x + y = -8[/tex] and [tex]2x - y = -10[/tex]
(9) [tex]3x - y = -54[/tex] and [tex]4x + y = -30[/tex]
(10) [tex]x + y = 2[/tex] and [tex]x - y = 2[/tex]
Step-by-step explanation:
Given [Missing from the question]
[tex](8).\ (-6,-2)\ \\ (9).\ (-12,18)\ \\ (10).\ (2,0)[/tex]
Required
Write a system of linear equations
The solutions to this question is open and have different solutions
Solving (8) (-6,-2)
Let the equations be: x + y and 2x - y
[tex]x + y = -6 - 2[/tex]
[tex]x + y = -8[/tex] --- (1)
[tex]2x - y = 2 * (-6) - (-2)[/tex]
[tex]2x - y = -10[/tex] -- (2)
So, the equations are:
[tex]x + y = -8[/tex] and [tex]2x - y = -10[/tex]
Solving (9) (-12, 18)
Let the equations be: 3x - y and 4x + y
[tex]3x - y = 3 *(-12) - 18[/tex]
[tex]3x - y = -54[/tex]
[tex]4x + y = 4 * (-12) + 18[/tex]
[tex]4x + y = -30[/tex]
So, the equations are:
[tex]3x - y = -54[/tex] and [tex]4x + y = -30[/tex]
Solving (9): (2,0)
Let the equations be: x + y and x - y
[tex]x + y = 2 + 0[/tex]
[tex]x + y = 2[/tex]
[tex]x - y = 2 - 0[/tex]
[tex]x - y = 2[/tex]
So, the equations are:
[tex]x + y = 2[/tex] and [tex]x - y = 2[/tex]

The expression x² − 17x − 60 can be factorized as (x + 3) (x- 20).
What is expression?An expression in math is a sentence with a minimum of two numbers/ variables and at least one math operation in it. Let us understand how to write expressions.
Constant: A constant is a fixed numerical value.Variable: A variable is a symbol that doesn't have a fixed value.Term: A term can be a single constant, a single variable, or a combination of a variable and a constant combined with multiplication or division.Coefficient: A coefficient is a number that is multiplied by a variable in an expression.Given:
x² − 17x − 60
Now, factorizing we get
x² − 20x + 3x − 60
= x(x − 20) + 3(x − 20)
= (x + 3) (x- 20)
Hence, the expression can be factorized as (x + 3) (x- 20).

hi can someone answer this
Answer:
B
Step-by-step explanation:
When two angles are on the interior like that, they are adding up to 180 degrees in total.
So, x would be 20 because
2x+60=
2 times 20, plus 60 = 100
and 3x+20=
And 3 times 20, plus 20 = 80
Adding up 100 and 80, you get 180 degrees.

Answer:
They have no relation, except for the fact that they intersect. If the equations were instead y = +5/4x - 1/2 and y = -4/5x + 2, or y = +4/5 + 2 and y = -5/4x -1/2, then they would be perpendicular.
Option 3 is the right answer.
Step-by-step explanation:
For the given lines y = -4/5x+2 and y = -5/4x - 1/2
we have to identify whether lines are parallel or perpendicular.
As we know if two lines are perpendicular then gradients of two lines will in the form of
m1 m2=(-1)
and if the lines are parallel then the gradients of the lines will be same.
m1=m2
Here m1 = -4/5 and m2 = -5/4
Therefore
m1m2=(-4/5)(-5/4)=(+1)
and
m1≠m2
So both the lines are neither parallel nor perpendicular to each other.
Option 3 is the right answer.
Solve the equation f(x) = -4x2 – 3x + 2 using the quadratic formula.
a. X=-1.17 and x = 0.43
b. x = 0.58 and x = 4.18
C. X = -4,X = -3, x = -2
d. x = 1.12 and x = 3.53
Need answer ASAP!
The solution f(x) = -4x2 – 3x + 2 is x=-1.17 and x = 0.43
The correct option is (A)
What is Quadratic equation ?Any equation containing one term in which the unknown is squared and no term in which it is raised to a higher power.
Given equation is :-4x²-3x+2
using the Quadratic Formula where
a = -4, b = -3, and c = 2
x = -b ±√b²-4ac/2a
= 3±√9+32/(-8)
= 3± √41/(-8)
x= 3/(-8) + √41/(-8) or x= 3/(-8)- √41/(-8)
x= -1.17 and x= 0.4253

explain rounding up numbers i dont mean only examples but definitions too
Answer:
Rounding up numbers means to make a number with many numerical values or digits into a more simpler way.
Step-by-step explanation:
In order to round up a number you have to look to the digit next to it and if its greater then five it rounds up, if it's less then five it stays the same. If the number only has one digit then you have to look at that number and round up by seeing if its greater than or less than five.
Examples:
[tex]7[/tex]
[tex]7>5[/tex]
[tex]7=10[/tex]
7 rounded up equals 10 because 7 is more near 10 then it is to one.
Round the number 12,371 to the nearest thousand.
This means to find the thousands place value (two) check the number next to the thousands place value (hundreds or three) and check to see if that number is greater then five or not.
[tex]12,371[/tex]
[tex]3 <5[/tex]
[tex]=12,000[/tex]
Therefore the 12,371 rounded to the nearest thousand is "twelve-thousand" and that's because three is not greater then or equal to five.

f of x equals one half times x plus 16
f of x equals one half times x plus 19
f(x) = 2x + 16
f(x) = 2x + 19
Answer:
Part 1) Option A. f of x equals one half times x plus 16
Part 2) Option A. x = 5
Part 3) Option C. x − 4y = −9
Part 4) Option A. The number of rides is the independent variable, and the total cost is the dependent variable.
Step-by-step explanation:
Part 1)
Let
x -----> the number of months
y ----> vertical jump in inches
step 1
Find the slope
we have the points
(0,16) and (2,17)
The equation of the line in slope intercept form is
we have
-----> the point (0,16) is the y-intercept

Answer:
Your function would be y = 1/2x + 16.
Explanation:
Points: (0, 16); (2, 17)
Slope: m = (17 - 16) / (2 - 0) = 1/2
Slope intercept form: y = mx + b
So, if the slope equals 1/2 and the y-intercept is (0, 16), you would use substitution to get y = 1/2x + 16.
Therefore, your ending function is y = 1/2x + 16.
Stock in Daenerys Industries has a beta of 1.2. The market risk premium is 5 percent, and T-bills are currently yielding 4.2 percent. The company's most recent dividend was $1.40 per share, and dividends are expected to grow at an annual rate of 5 percent indefinitely. If the stock sells for $30 per share, what is your best estimate of the company's cost of equity?
Answer:
The best estimate of the company's cost of equity is 10.05%.
Step-by-step explanation:
Using growth rate model formula, the cost of equity can be calculated as follows:
Cost of equity as per growth rate model = (D1 / P) + g ................ (1)
D1 = Most recent dividend * (1 + g) = $1.40 * (1 + 0.05) = $1.47
P = Current price per share = $30
g = Growth rate of dividend = 5%, or 0.05
Substituting the values into equation (1), we have:
Cost of equity as per growth rate model = ($1.47 / $30 ) + 0.05
Cost of equity as per growth rate model = 0.099. or 9.90%
Using Capital Asset Pricing Model (CAPM) formula, the cost of equity can be calculated as follows:
Cost of equity as per CAPM = Risk free rate + (Beta * Market risk premium) = 4.2 + (1.2 * 5) = 10.20%
Therefore, we have:
Best estimate of Cost of equity = (Cost of equity as per growth rate model + Cost of equity as per CAPM) / 2 = (9.90% + 10.20%) / 2 = 10.05%
Therefore, the best estimate of the company's cost of equity is 10.05%.

A prism is filled with 70 cubes with a side length of 1 2 unit. What is the volume of the prism in cubic units? Enter answer as a mixed number in its simplest form.
Answer:
The volume of the cube is;
[tex]8\dfrac{3}{4} \ cube \, units[/tex]
Step-by-step explanation:
The parameters of the prism are;
The number of cubes used to fill the prism, n = 70 cubes
The side length of each cube, s = 1/2 unit
The volume of the cube, V = n × s³
