Answer:
y = ![-\frac{4x-5}{2}](https://tex.z-dn.net/?f=-%5Cfrac%7B4x-5%7D%7B2%7D)
Step-by-step explanation:
Step 1: Switch sides
5 - 2y = 4x
Step 2: Subtract 5 from both sides
5 - 2y - 5 = 4x - 5
Step 3: Simplify
-2y = 4x - 5
Step 4: Divide both sides by -2
![\frac{-2y}{-2} = \frac{4x}{-2} - \frac{5}{-2}](https://tex.z-dn.net/?f=%5Cfrac%7B-2y%7D%7B-2%7D%20%3D%20%5Cfrac%7B4x%7D%7B-2%7D%20-%20%5Cfrac%7B5%7D%7B-2%7D)
Step 5: Simplify
y = ![-\frac{4x-5}{2}](https://tex.z-dn.net/?f=-%5Cfrac%7B4x-5%7D%7B2%7D)
It is important to write a number as a product of primes because on many tests, you will be asked to write the "prime factorization". Also, any time you are asked a question about multiples or factors, you bet using prime factorization will get you your answer quicker!<span>

I think is 4.7 for SU, pls let me know if is right :).
Answer:
The hawk reaches the rabbit at t=4.3 sec
Step-by-step explanation:
Let
h ----> is the height in feet
t ----> is the time in seconds
v ---> the initial velocity in feet pr second
s ----- is the starting height
we have
![h=-16t^{2} +vt+s](https://tex.z-dn.net/?f=h%3D-16t%5E%7B2%7D%20%2Bvt%2Bs)
when the hawk reaches the rabbit the value of h is equal to zero
we have
![v=55\ ft/sec](https://tex.z-dn.net/?f=v%3D55%5C%20ft%2Fsec)
![s=60\ ft](https://tex.z-dn.net/?f=s%3D60%5C%20ft)
substitute
![0=-16t^{2} +55t+60](https://tex.z-dn.net/?f=0%3D-16t%5E%7B2%7D%20%2B55t%2B60)
