Answer:

Step-by-step explanation:

Answer:
The inverse is 5x+3
Step-by-step explanation:
y = (x-3) /5
Exchange x and y
x = (y-3)/5
Solve for y
Multiply each side by 5
5x =(y-3)/5 *5
5x = y-3
Add 3 to each side
5x+3 =y-3+3
5x+3 =y
The inverse is 5x+3
Table:
<span>Years (x) 1 2 3 4 5 6
Money (y) (hundreds of dollars) 15 30 45 60 75 90
</span>
y = 15(x)
y = 15(9)
y = 135 hundreds of dollars
<span>y = 15x, in 9 years he will have saved $13,500</span>
