<h3>What is a line?</h3>

A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely.

The slope of the parallel line is always equal. Given the slope of the green line is -3/7, also, it is parallel to the red line. Therefore, the slope of the red line is -3/7.

Hence, the correct option is A.

(HELP)matt weighed 60 pounds when he was 8 he now weighs 80 pounds. Find the percent of increase in weight rounded to the neares
meriva

Answer:

Percent of increase in weight = 33.33% Approx.

Step-by-step explanation:

Given:

Old weight = 60 pound

New weight = 80 pound

Find:

Percent of increase in weight

Computation:

Percent of increase in weight = [(New weight - old weight)/Old weight]100

Percent of increase in weight = [(80 - 60)/60]100

Percent of increase in weight = [(20)/60]100

Percent of increase in weight = 33.33% Approx.

Please help <br> X-2<br> If = k and k = -4, what is the value of x?<br> 5
SashulF [63]

Answer:

C

Step-by-step explanation:

So we have the equation:

\frac{x-2}{5}=k

And we want to find the value of x such that k is -4.

To do so, we can substitute -4 for k and then solve for x.

So, substitute -4 for k:

\frac{x-2}{5}=-4

And now, we just have to solve for x.

Let's multiply both sides by 5:

(5)\frac{x-2}{5}=5(-4)

The left side cancels. Multiply on the right:

x-2=-20

Now, let's add 2 to both sides:

(x-2)+2=(-20)+2

The left side cancels again. Add on the right:

x=-18

Therefore, the value of x is -18.

Our answer is C.

And we're done!
