Answer:

So first we need to do 2*(-2) thats easy because anything times 2is 2x. So the first one is -2+-2 or -4. The next one is also easy because anything times 1 is x so it will be -2. Next we know that 2 minuses become positive so -1*-2 = 1*2 = 2. And same goes for the next one, they cancel out yielding 2*2 = 4

Hat is the slope of the linear relationship shown in this table of values?
dlinn [17]

By using any two of the points in the table, we will see that the slope is -2.

<h3>How to get the slope for the linear relationship?</h3>

A general linear relationship is:

y = a*x + b

Where a is the slope and b is the y-intercept.

Remember that if the line passes through (x₁, y₁) and (x₂, y₂), the slope is:

a = \frac{y_2 - y_1}{x_2 - x_1}

Here we can use the first two points on the table:

(-4, 11) and (2, -1), so the slope is:

a = \frac{11 - (-1)}{-4 - 2}  =  12/-6 = -2

Then the slope of the line is -2.

Morgan is reupholstering an old chair with two circular cushions. Each cushion has a circumference of 7. 85 feet. He will need t
kramer

The total fabric Morgan needs to cover the cushions will be 19.64 square feet.

It is given that each cushion has a circumference of 7.85 feet.

It is known that the circumference of a circle = 2πr, where 'r' is the radius of the circle.

2πr = 7.85

r = 1.25

<h3>What is an area of a circle?</h3>

area of a circle is πr².

now, we can calculate the area = π× 1.25² = 4.91 square feet

since each circular cushion has two circular faces so the total number of faces Morgan needs to cover will be 4.

Therefore, the total fabric needed= 4×4.91 = 19.64 square feet.
