Answer:

28 miles

Step-by-step explanation:

Let w stand for the number of miles Derrick runs each week. Then after 4 weeks of training, he wants the total mileage to be 100 miles.

16 + 3w = 100

3w = 84 . . . . . . . subtract 16

PLEASE HELP ASAP!!!

Answer:

Option C. Yes; y=2x

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form $k=\frac{y}{x}$ or $y=kx$

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

In this problem

For x=0, y=0

That means ----> the line passes through the origin

Find the value of k

For x=2, y=4

$k=\frac{y}{x}$ ----> $k=\frac{4}{2}=2$

For x=4, y=8

$k=\frac{y}{x}$ ----> $k=\frac{8}{4}=2$

The values of k are equal

therefore

The table represent a direct variation

The equation is equal to

$y=2x$
