N=-2
Add 42 to both sides to get -6n=12
Divide both sides by -6
Answer:
C
Step-by-step explanation:
Answer:
2 is not a solution
Step-by-step explanation:
x < -12
<u>Step 1: Check if 2 is less than -12</u>
2 < -12
No, this doesn't work
Answer: 2 is not a solution
You can turn 5 into 10/2 and add to x/2
then you need to use simple algebra to left the x alone in the equation so you need to multiply both sides by 2 so you get
2y=10+x
then you need to subtract both sides a 10 so
2y-10=x
now change the x to f'(x) and y to x so:
f'(x)=2x-10
First you have to figure out the length of the track:

r is the half of the diameter:
200ft : 2 = 100ft

= 200

≈
628,31
The athlete has to run ca. 5280ft for one mile:
5280 : 628,31≈8,4
The athlete has to run 8,4 laps
