The multiplier that would be used to calculate the depreciation of the car is 0.83^y.
What does depreciation mean?Depreciation is when the value of an asset declines due to wear and tear.
The equation that can be used to represent depreciation is:
Value of the asset x (1 - rate of depreciation)^years
$31,000 x 0.83^y.

For what value of y does 125 = (StartFraction 1 Over 25 EndFraction) Superscript y minus 1? Negative five-halves –2 –1 Negative one-half.
Answer:
D. -1/2
Step-by-step explanation:
First to rewrite the equation in numbers
[tex]125=\frac{1}{25}^{y-1}[/tex]
First, we need to find what exponent would get 1/25 to 125.
[tex]\frac{1}{25}^{y}=125[/tex]
Sense 1/25 is a fraction we must use a negative exponent to make it a whole number. We can just find what exponent would get 25 to 125 then make it negative. 1 wouldn't be enough and 2 would be too much so y is between 1 and 2 into negative is between -1 and -2. Sense the original equation has (y-1) the only option you can subtract 1 from to get between -1 and -2 is -1/2 which would give -1 1/2.
Answer:
Keep it simple: D or -1/2

Use the model below to determine x, the amount each child
spent at Taco Bell.
Answer:
x = 5
Step-by-step explanation:
The model tells you ...
4x = 20
x = 20/4 = 5 . . . . . divide both sides by 4

Which expression represents the following word sentence? Four times the sum of 3. 2 and a number is the number less 1. 4. 4n 3. 2=1. 4−n 4(3. 2 n)=n−1. 4 4(n 3. 2)=1. 4−n.
The line four times the sum of 3.2 and a number is the number less 1.4 can be expressed as 4(n+3.2) = n-1.4.
What is an Expression?In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
Given to us
Four times the sum of 3.2 and a number is the number less than 1.4
Let the number be n.
It is given that the sum of 3.2 and number,
n + 3.2
Four times the sum, therefore,
4(n+3.2)
The total we got is the number less 1. 4. thus,
4(n+3.2) = n - 1.4
Hence, the line four times the sum of 3.2 and a number is the number less 1.4 can be expressed as 4(n+3.2) = n-1.4.

f(x) = -9x + 7 find f(3) HELPPP
The given function is ,
→ f(x) = -9x + 7 .
And we need to find out its value at x = 3 , that is f(3) . So just substitute x = 3 ,
→ f(3) = -9*3 +7
→ f(3) = -27+7
→ f(3) = -20
Hence the required answer is-20 .

How do I find the slope of the line?
Answer:
The slope of a line characterizes the direction of a line. To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points.
Step-by-step explanation:
yeah
Answer:
Pick two points on the line and determine their coordinates. Determine the difference in y-coordinates of these two points (rise). Determine the difference in x-coordinates for these two points (run). Divide the difference in y-coordinates by the difference in x-coordinates (rise/run or slope).

is x =4 a solution of the equation
13=2x + 4?
A.yes
B.no
No, it is not. If you plug 4 into the equation in the place of x, you get 13=2(4)+4
13=8+4
13=12
It equals 12, not 13.
Answer:
No
Step-by-step explanation:
Because If You Do 2 x 4 you get 8 and 8 + 4 = 12 and not 13 so the answer is 4.5 because 4.5 x 2 = 9 and 9 + 4 = 13

Slope formula: [tex]m=\frac{y_2-y_1}{x_2-x_1}\\[/tex]
Substitute the known values for their respective variables and solve for the missing coordinate, r.
[tex]m=\frac{y_2-y_1}{x_2-x_1}\\\\ -\frac{1}{2}=\frac{6-r}{-12-(-4)}\\\\-\frac{1}{2}=\frac{6-r}{-8}\\\\ -8(-\frac{1}{2})=(\frac{6-r}{-8})-8\\\\ 4=6-r\\\\4-6=6-r-6\\\\-2=-r\\\\\frac{-2}{-1}=\frac{-r}{-1}\\\\ 2=r[/tex]
