H(t) = -16t² + 16 t + 480
Factor out -16
-16(t² - t - 30)
t² - t - 30
(t + 5)(t - 6) ⇒ t(t-6) + 5(t-6) ⇒ t² -6t + 5t - 30 ⇒ t² - t - 30
t + 5 = 0 t - 6 = 0
t = -5 t = 6
The value of t is either -5 or 6 however time can't be measured in negative form; then, it took Rose 6 seconds to hit the water.
Answer:
y = 4x +1
Step-by-step explanation:
6x + 1 = y + 2x
First you need to solve for y, so then you need to
1. Combine like terms
So since there isn't anything to combine we can more on.
2. Make Y by itself
You need to subtract the 2x from both side to get the answer
y = 4x +1
