You use Pythagoras theorem for this:
You add 52 and 20 for AC which is 72
So you do
X^2 = 72^2 + 30^2
X^2 =5184 + 900
X^2= 6084
X = 6084 squared root
X= 78
Simple...
you have: 27-9x+15
Add any terms that are the same-->>
-9x+42
Factor-->>>
-3(3x-14)
Thus, your answer.
The y-intercept is (0, -12).
Hope that helped. :)
Answer:
c = $130
Step-by-step explanation:
Given:
c = 100 + 0.30m
Where,
c = cost of renting a car (in dollars)
m = number of miles driven (in miles)
If m = 100 miles
c = 100 + 0.30m
= 100 + 0.30(100)
= 100 + 30
= 130
c = $130
