Answer:
y = 4x + 5
Step-by-step explanation:
anything with the slope of 4x is parallel to the given equation. therefore, there are an infinite amount of answers.
<u>so, y = 4x + any number</u>

Answer:
So, the times the ball will be 48 feet above the ground are t = 0 and t = 2.
Step-by-step explanation:
The height h of the ball is modeled by the following equation
![h(t)=-16t^2+32t+48](https://tex.z-dn.net/?f=h%28t%29%3D-16t%5E2%2B32t%2B48)
The problem want you to find the times the ball will be 48 feet above the ground.
It is going to be when:
![h(t) = 48](https://tex.z-dn.net/?f=h%28t%29%20%3D%2048)
![h(t)=-16t^{2}+32t+48](https://tex.z-dn.net/?f=h%28t%29%3D-16t%5E%7B2%7D%2B32t%2B48)
![48=-16t^{2}+32t+48](https://tex.z-dn.net/?f=48%3D-16t%5E%7B2%7D%2B32t%2B48)
![0=-16t^{2}+32t+48 - 48](https://tex.z-dn.net/?f=0%3D-16t%5E%7B2%7D%2B32t%2B48%20-%2048)
![16t^{2} - 32t = 0](https://tex.z-dn.net/?f=16t%5E%7B2%7D%20-%2032t%20%3D%200)
We can simplify by 16t. So
![16t(t-2)= 0](https://tex.z-dn.net/?f=16t%28t-2%29%3D%200)
It means that
16t = 0
t = 0
or
t - 2 = 0
t = 2
So, the times the ball will be 48 feet above the ground are t = 0 and t = 2.
