I’m sorry my answer was wrong
The answer to number 13) x-4
Answer:
A.)
Step-by-step explanation:
It is not a function if 2 or more ordered pairs share the same x-value.
Answer:
16
Step-by-step explanation:
3/4y-7=5
*multiply both sides of the equation by 4
= 3y-28=20
*move <u>constant</u> to the right-hand side and change its sign
=3y=20+28
*add the numbers <u> </u>
=3y=48
*divide both numbers by 3
and that's how you get 16
For this case we have the following equation:
h = -16t2 + 64t + 80
To find the maximum height, we derive the equation:
h = -32t + 64
We match zero:
-32t + 64 = 0
We clear t:
t = 64/32
t = 2
We substitute the value of t in the given equation:
h (2) = -16 * (2) ^ 2 + 64 * (2) + 80
h (2) = 144
Answer:
The maximum height is 144 feet and the time to reach this height is 2 seconds.
