Answer:
20 inches
Step-by-step explanation:
Answer:
y= -2x +39
Step-by-step explanation:
y= mx+b
m is the slope which is given -2
since we don't know b we can solve the rest using the formula y-y1{ m(x-X1(
y - 15 = -2(x-12)
simplify
y-15= -2x +24
y= -2x + 39
For this case we have to:
Let
So:

We have the solution will be given by:

Where:

Substituting:

The solutions are:

Returning the change:
