Answer:
f(-3) = 15
Step-by-step explanation:
Given that,
f(x) = -x + 12
You have to solve for,
f(-3) = ?
For that,
you have to put (-3) instead of x
f (-3) = -x + 12
= -(-3) + 12
= +3 + 12
= 15

Answer:
3 hours
Step-by-step explanation:
After one hour, car a will be only 20 miles ahead of car b, after two hours, car a will only be 10 miles ahead of car b, and after 3 hour, they will both be equal. This is because car b is going 10 mph faster than car a, because 70-60=10. every hour, car b will catch up to car a by 10 miles.

In a 30-60-90 triangle, if the hypotnuse is length 2x then the side oposite the 30 degree angle is x and the other side is x√3
so if hyptohuse is 30 then 30=2x and 15=x
the shortest side is x
