Mathematics
1 answer:
Goryan [66]3 years ago

Answer:

(TAKE THE MINUS OUT)

Step-by-step explanation:

The first thing he has to do is take that "minus" sign through the parentheses containing the second polynomial. Some students find it helpful to put a " 1 " in front of the parentheses, to help them keep track of the minus sign. Here's what the subtraction looks like, when working horizontally.

forsale [732]

Answer:

21.43 miles

Step-by-step explanation:

Let

x ---> the number of miles

y ---> the total cost of rent a car per day

we know that

The linear equation in slope intercept form is equal to

y=mx+b

where

m is the slope

b is the y-intercept

we have

<em>sunshine rental company</em>

The slope is equal to

m=\$0.50\ per\ mile

The y-intercept is equal to

b=\$17

substitute

y=0.50x+17 ----> equation A

<em> rent me company</em>

The slope is equal to

m=\$0.36\ per\ mile

The y-intercept is equal to

b=\$20

substitute

y=0.36x+20 ----> equation B

equate equation A and equation B

0.50x+17=0.36x+20

solve for x

0.50x-0.36x=20-17\\0.14x=3\\x=21.43\ miles
