we know that

A line has a slope of \frac{4}{3}

The formula to calculate the slope between two points is equal to

m=\frac{y2-y1}{x2-x1}

we will proceed to calculate the slope in each case and compare with the slope of the given line to determine the solution

<u>case A)</u> (24, 19)\ (8, 10)

substitute in the formula

m=\frac{10-19}{8-24}

m=\frac{-9}{-16}

m=\frac{9}{16}

\frac{9}{16} \neq \frac{4}{3}

therefore

case A) is not the solution    

<u>case B)</u> (10, 8)\ (16, 0)

substitute in the formula

m=\frac{0-8}{16-10}

m=\frac{-8}{6}

m=-\frac{4}{3}

-\frac{4}{3} \neq \frac{4}{3}

therefore

case B) is not the solution    

<u>case C)</u> (28, 10)\ (22, 2)

substitute in the formula

m=\frac{2-10}{22-28}

m=\frac{-8}{-6}

m=\frac{4}{3}

\frac{4}{3} = \frac{4}{3}

therefore

case C) could be the solution    

<u>case D)</u> (4, 20)\ (0, 17)

substitute in the formula

m=\frac{17-20}{0-4}

m=\frac{-3}{-4}

m=\frac{3}{4}

\frac{3}{4} \neq \frac{4}{3}

therefore

case D) is not the solution  

<u>the answer is</u>

The line could be through the points (28, 10)\ (22, 2)

If Wendell creates a scale drawing using the scale 1 inch to 10 feet, what will the dimensions of the deck in the scale drawing
jolli1 [7]

Answer:

The dimensions on the scale drawing would be 1 inch by 0.8 inches.

The scale is 1 in: 10 ft; since the actual width of the deck is 10 ft, then it will be 1 inch on the scale.  To find the width:

1/10 = x/8

Cross multiply:

1*8 = 10*x

8 = 10x

Divide both sides by 10:

8/10 = 10x/10

0.8 = x

The width on the scale drawing will be 0.8 inches.

Area= (10+28)/2 * 23
Area= 38/2 * 23
Area= 19*23
= 437

Fiona has $18 to spend. She spent $4.25, including tax, to buy a notebook. She needs to save $9.75, but she wants to buy a snack
Irina18 [472]
1. 18-4,25=13,75 \\ 13,75-9,75=4 \\ 0,50x \leq 4 <u />⇔x= \frac{4}{0,50}⇔x= 8
R: She can buy 8 crackers

2. Amy used 13%
Dan used 0,14*100 = 14%
Mike used 0,5*100 = 50%
R: Mike used the greatest amount of milk.
