Parallel lines have the same slope.  Since our reference line has a slope of -1, so will a line parallel to it.  Thus far we have:

y=-x+b, using point (7,1) we can solve for b

1=-7+b

8=b  so the parallel line passing through (7,1) is:

y=-x+8

To graph ( 0, 15 ) what is the only direction you will move
Dominik [7]

Pleaseeeee help me with this!!

Answer:

The correct option is C.

Step-by-step explanation:

The bike shop owner rents out bikes and scooters.

The cost to rent a bike is $15 plus $8 per hour for each hour the bike is rented.

Rent of bike = Fixed rent + Variable rent

The rent function of a bike is

f(x)=15+8t

Where, t is number of hours.

The cost to rent a scooter is $35 plus $5 per  hour for each hour the scooter is rented.

The rent function of a scooter is

f(x)=35+5t

Where, t is number of hours.

The slope intercept form of a line is

y=mx+b

Where, m is slope and b is y-intercept.

So by slope intercept form the rate of change of bike is $8 and rate of change of scooter is 5.

8>5

Therefor option C is correct.

The length of a rectangle is five inches less than twice it’s width. If the rectangle has a perimeter of 80 inches, find the len
yawa3891 [41]

Answer:

Width of the rectangle  = 15 inches

Length of the rectangle  = 25 inches

Step-by-step explanation:

Let the width of the rectangle =  k inches

So, the length of the rectangle =   (2k -5) inches

Perimeter = 80 in

Perimeter of a rectangle = 2 (Length + Width)

⇒  80 = 2(k + (2k -5)

or 80 = 6k - 10

⇒ 6k = 80 + 10 = 90

or  k = 90 / 6

⇒ k = 15

So the width of the rectangle  = k  = 15 inches

And the length of the rectangle =  2k -5 = 2 x 25  - 5 = 25 inches
