Answer:
C(t) = $28,000(0.811)^t (Answer A)
Step-by-step explanation:
The value of the car is decreasing. Thus, by the end of the first year of ownership, the car will have the value $28,000(1 -0.189)^1, where the "-0.189" represents DECAY instead of GROWTH.
Please use " ^ " to indicate exponentiation.
Then the desired formula is C(t) = $28,000(0.811)^t (Answer A)
Answer: y = 2x + 12
Explanation: The slope-intercept form is y = mx + b, where m is slope and b is the y-intercept. Substituting 2 for m, 6 for x, and 24 for y, we have 24 = 2(6) + b. Simplifying, we get that b = 12, so the equation is y = 2x + 12.

14x + -21xy
Factor out the Greatest Common Factor (GCF), '7x'.
7x(2 + -3y)
Final result:
7x(2 + -3y)

Alright so the parentheses mean (x, y) so basically you have to plug in the numbers in parentheses into the equation so here's what I got:
a. i
b. iv
c. ii
d. v
So then e must be iii, let’s check:
y = -x + 1
.5 = -.5 + 1 ✔️
.75 = -.25 + 1 ✔️
.875 = -.125 + 1 ✔️
So that’s how you would solve those equations. Hope this helps.
To find the surface area of this figure, we simply have to add up the individual areas of the shapes that make up the figure.
Surface area = 4(area of triangle) + area of square
Surface area = 4 ( 1/2 * base * height) + side^2
Surface area = 4( 1/2 * 6 * 7) + 6^2
Surface area = 4 (3 * 7) + 36
Surface area = 4(21) + 36
Surface area = 84 + 36
Surface area = 120 cm^2
Hope this helps!
