Ihave to turn this in tomorrow, we are learning about y and x intersects

The first one one would 42x+500 for Bill. Becauseee Bill is going 50 feet per minute. And x is minute.
For Bill is would be just be 50x

50x=42x+500
-42x
8x=500
_ _
8 8

X=62.5

(Btw I am not 100 percent sure if this is how you would solve this. But this is better than nothing on your worksheet . Hope it’s right!)

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
