A rental car agency charges $30.00 per day

lutik1710 [3]

<h2>Answer:</h2><h2>They should travel 120 mils in one day for both rental agencies to cost the same amount to rent</h2>

Step-by-step explanation:

A rental car agency charges $30.00 per day plus per mile $0.15.

Let x be the number of miles travelled by car

Their total cost = 30 + (0.15x) ... (1)

Another rental car agency charges $36.00 per day plus $0.10 per mile

Their total cost = 36 + (0.10x) ... (2)

Equating (1) and (2), we get

30 + (0.15x) = 36 + (0.10x)

36 - 30 = 0.15x - 0.10x

6 = 0.05x

x = 120 miles

They should travel 120 mils in one day for both rental agencies to cost the same amount to rent

Help please! Identify an equation in point slope form for the line perpendicular to Y =-4x + 8 that passes through (-2, 7)

777dan777 [17]

Answer:

D. $y-7=\frac{1}{4}(x+2)$

Step-by-step explanation:

The point-slope form of a line is given by:

$y-y_1=m(x-x_1)$

The line given to us has equation; $y=-4x+8$ .

The slope of this line is -4. The of the line perpendicular to this line is the negative reciprocal of the slope of the given line.

Our slope of interest is therefore; $m=\frac{1}{4}$

Since the point goes through (-2,7), we have $x_1=-2,y_1=7$ .

We plug in the slope and the point into the point-slope formula to obain;

$y-7=\frac{1}{4}(x--2)$

The required equation is:

$y-7=\frac{1}{4}(x+2)$
