Answer:

The slope is 3/4

Please correct me if I am wrong please and thank you

Step-by-step explanation:

I use the slope formula \frac{y2-y1}{x2-x1}

Plug in (2,1) and (-2,-2)

1-(-2)/2-2

= 3/4

Answer:

3/4

Step-by-step explanation:

The slope of this line is 3/4. Slope is the rise over run or the change in y over the change in x. So one way to find the slope is to count how much y and x changes, in this graph between the 2 points y increases by 3 and x increases by 4. So the final slope is 3/4, (if one value decreases then the slope is negative). One way to visually check the slope is to remember that slopes less than -1 or greater than 1 make the line steeper while fraction slopes make the line flatter. Also, you can use the slope formula, \frac{y_{2-y_{1} } }{x_{2}-x_{1}  } just plug in the values.

One quart of water-resistant paint covers 75 square feet. A swimming pool is in the shape of a rectangular prism with a length o
docker41 [41]

18.66 quarts of paint is needed to paint the swimming pool with two coats of paint

<em><u>Solution:</u></em>

Given that,

<em><u>A swimming pool is in the shape of a rectangular prism</u></em>

Length = 20 feet

Width = 10 feet

Height = 5 feet

<em><u>Find the surface area of prism</u></em>

A=2(wl+hl+hw)

Where, "l" is the length and "w" is the width and "h" is the height

A = 2(10 \times 20 + 5 \times 20 + 5 \times 10)\\\\A = 2(200+100+50)\\\\A = 2 \times 350\\\\A = 700

Thus surface area area of prism is 700 square feet

Given that,

One quart of water-resistant paint covers 75 square feet

Therefore,

1 quart paint = 75 square feet

x quart = 700 square feet

This forms a proportion

1 \times 700 = 75 \times x\\\\x = \frac{700}{75}\\\\x = 9.33

Thus 9.33 quarts of paint is needed to cover 700 square feet

How many quarts should you buy to paint the swimming pool with two coats of paint

For two coats of paint we need = 9.33 + 9.33 = 18.66 quarts of paint

110 + 3x +11 = 16x + 4 solve for x
sashaice [31]

Answer:

x = 9

Step-by-step explanation:

110 + 3x + 11 = 16x + 4

121 + 3x = 16x + 4

<u>        -3x    -3x</u>

121 = 13x + 4

<u>-4             - 4</u>

117 = 13x

117 ÷ 13 = x

9 = x

Check:

110 + 3(9) + 11 = 16(9) + 4

121 + 27 = 144 + 4

148 = 148
