Answer:
f(9) = -37
Step-by-step explanation:
f(n) = -5n + 8
f(9) = -5(9) + 8
f(9) = -45 + 8
f(9) = -37
The height is 33.
Set up the equation like this,
1056 = 32 h
Solve the one step equation and get 33.
Hope this helps!
You set 49 equal to 8x - 15
So
8x - 15 = 49
+15 + 15
8x = 64
Then divide by 8
X= 8
I think that is is 8.3, but I could be incorrect!
