Answer:

slope = k/2

Step-by-step explanation:

The slope formula is useful for finding slope.

m = (y2 -y1)/(x2 -x1)

m = (5k -7k)/(-3 -1)

m = -2k/-4

m = k/2

The slope is k/2.

$1\ hr = 10\ miles$

Required

The graph that shows the number of miles in x hours

We have:

$1\ hr = 10\ miles$

The perimeter of a rectangular field is 168 feet. The field is 36 feet wide. How long is the field

Dmitriy789 [7]

To find the length, divide the peremiter by 2 and then subtract the width.

Length= Peremiter/2 - width
L = P/2 - W
L = 168/2 - 36
L = 84 - 36
L = 48

The length is 48
