345 ft/min * 60 min/hr = 345*60 ft/hr =20700 ft/hr
Answer:
105
Step-by-step explanation:
f(x) = 8x² + x -9
g(x) =5x²
(f+g)(x) = 8x² + x - 9 + 5x²
Collect like terms
8x² +5x² + x - 9
13x² + x - 9
b) (f+g)(-3) = 13x² + x - 9 when x =-3
= 13×-3² + (-3) - 9
= (13×9) -3 -9
= 117 -3 -9
= 105

Hey !
Slope = 6-8/8-4 = -2/4 = -1/2 = -0.5
Set up a ratio to compare the values, then solve for the missing value (y):
:

First, change

to

/ Your problem should look like:
Second, multiply both sides by 8. / Your problem should look like:
Third, divide both sides by 5. / Your problem should look like:

Answer as fraction: y =
