Answer:
f ^-1 (x) = 2x+28
Step-by-step explanation:
f(x) = 1/2x-14
Replace f(x) with y
y = 1/2 x -14
Exchange x and y
x = 1/2 y -14
Solve for y
Add 14 to each side
x+14 = 1/2 y -14+14
x+14 = 1/2 y
Multiply each side by 2
2(x+14)= 1/2 y*2
2x+28 = y
The inverse function is
f ^-1 (x) = 2x+28
There are 3 shorter boards because if you divide 27 by 9 it equals 3.
Answer: 8, 15, 22, 29, 36, 43
Step-by-step explanation: So we add 7 each time so 8+7=15
15+7=22
22+7=29
29+7=36
36+7=43
