Answer:
![\sqrt[6]{z}](https://tex.z-dn.net/?f=%5Csqrt%5B6%5D%7Bz%7D)
Step-by-step explanation:
The denominator of the fractional exponent is the index of the root.
Ava took 5 minutes out of 60 in an hour to do half a mile
5×2=10
60/10=6mph
Damon took 3 minutes out of 60
3×2=6
60/6= 10mph
Reina took 4 minutes out of 60
4×2=8
60/8= 7.5mph
It would be answer choice A (10^5) because there are 5 10s in the problem
Since slope intercept is y=mx+b, you first want to get rid of the 2x by subtracting it from both sides. after, you should end up with 4y=16-2x or 4y=-2x+16, they both are the same, but some teachers might prefer the slope first. after that, you want to get the y alone, so you divide everything by 4. you should end up with the slope intercept form being y=-2/4x+4, simplified to y=-1/2x+4.
The answer is A, the first one :)
