Answer:

<h2>length = 22 inches</h2><h2>width = 8 inches</h2>

Step-by-step explanation:

Perimeter of a rectangle = 2l + 2w

where

l is the length

w is the width

From the question

Perimeter = 60 in

The statement

the length of a rectangle is 6 inches more than twice it's width is written as

l = 6 + 2w

Substitute the statement into the above formula

That's

60 = 2( 6 + 2w) + 2w

60 = 12 + 4w + 2w

6w = 60 - 12

6w = 48

Divide both sides by 6

w = 8

Substitute w = 6 into l = 6 + 2w

That's

l = 6 + 2(8)

l = 6 + 16

l = 22

The dimensions are

length = 22 inches

width = 8 inches

Hope this helps you

The function on the table is decreasing on the interval [-2, 0).

<h3>Over what interval is the function shown in the table decreasing?</h3>

A function is decreasing if, as x increases, f(x) decreases.

We can see that at x = -2, f(-2) = 12.

Then at x = 0, f(0) = 0.

And for the value after that:

x = 1, f(1) = 3

So now the function increases. Then we conclude that the function is decreasing on the interval [-2, 0), and after that the function increases.

What is the y-intercept of the line 3x-4y=24
Contact [7]

Answer:

(0,-6)

Step-by-step explanation:

3x-4y=24

To find the y intercept, let x =0 and solve for y

3(0) -4y =24

-4y =24

Divide by -4

-4y/-4 = 24/-4

y = -6

The y intercept is

(0,-6)
