Answer:
asdasdasdasdasdasdasdasdasd
Step-by-step explanation:
<span>h = -8t² + 40t
dh/dt = 0
⇒ d/dt(</span><span>-8t² + 40t) = 0
⇒ -16t + 40 = 0
⇒ 16t = 40
⇒ t = 40/16 = 2.5s
So it takes 2.5 seconds to reach highest point
h = -8×2.5² + 40×2.5 = -50 + 100 = 50
Ordered pair: (h,t) = (50,2.5)
</span>
First step is Add 3 to both sides

Answer:
x=-5
Step-by-step explanation:
I did a for #42
2(x-5)=3x+5
simplify
2x-10=3x+5
subtract 2x from both sides
-10=3x+5
subtract 5 from both sides
-15=3x
divide both sides by 3
-5=x
