Answer:
T=12500-0.25y
Step-by-step explanation:
Step one:
given data
The value of the car is $12500.
let the value of the previous year be T
let the number of years be y
25% will be 0.25----this is equivalent to the gradient
The expression for the change in price can be represented linearly using the equation of a straight line,
y=mx+c
but since the price is reducing the expression becomes
y=-mx+c
Now, in this situation the expression for the cost after y years is
T=-(0.25y)+12500
rearrange
T=12500-0.25y
<u>The expression is T=12500-0.25y</u>
3 because (l*w*h =v) and 3^3 is 27
Answer:
A
Step-by-step explanation:
Given
x² = 27 ( take the square root of both sides )
x = ±
= ±
= ± ×
= ± 3 → A
Answer:
T=-12
Step-by-step explanation:
Isolate variable by subtracting 4 on both sides
t=-12
3 (300000+90000+500000+440)
then just add 10000 to get 2,681,320
