Answer:

y=3/4x-11

Step-by-step explanation:

When a line is perpendicular to another line, their slope is the opposite reciprocal of that. So in this case, the slope of the perpendicular line would be positive 3/4. Next, plug in the points (8,-5) in the y=mx+b formula along with the new slope. In conclusion, the new point slope formula is y=3/4x-11.

Hope this helps! :)

Determine whether or not the relation is a function. Please help asap
OLga [1]

Answer:

A function can have many x values for a given y value and still be a function but it cannot have many y values for a given x value. You can easily test this by graphing the equation and doing the vertical line test by seeing if a vertical line will intersect the graph only once at all x values, if it passes it is a function. In short what you have here is a function

Prestige car rentals charge $44 per day plus 6 cents per mile to rent a mid sized vehicle. Gateway auto charges $35 per day plus
bulgar [2K]

Answer:

300 miles

Step-by-step explanation:

Let

x ----> the number of miles

y ----> the total cost for rent a car

we know that

The equation of the line in slope intercept form is equal to

y=mx+b

where

m is the slope or unit rate

b is the y-intercept or initial value

<u><em>Prestige car rentals</em></u>

we have that

The slope is equal to m=\$0.06\ per\ mile

The y-intercept is b=\$44

therefore

y=0.06x+44 -----> equation A

<u><em>Gateway auto</em></u>

we have that

The slope is equal to m=\$0.09\ per\ mile

The y-intercept is b=\$35

therefore

y=0.09x+35 -----> equation B

For what number of miles both companies charge the same price>

Equate equation A and equation B

0.09x+35=0.06x+44

solve for x

0.09x-0.06x=44-35\\0.03x=9\\x=300\ miles
