slope = - 4

To calculate the slope m use the gradient formula

m = ( y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (4, 9 ) and (x₂, y₂ ) = (6, 1 )

m = \frac{1-9}{6-4} = \frac{-8}{2} = - 4

Dahasolnce [82]
<h2>Greetings!</h2>

Answer:

x = 67.5

Step-by-step explanation:

Because AB and NP lines are parrallel, we can find out the scale factor by dividing size MA by MN.

This works because you find out what the MA size has to be multiplied to to get to MN, which will also work in reverse to find angle MB from MP.

71.5 - 22 = MA = 49.5

71.5 ÷ 49.5 = \frac{13}{9}

So to get to line MP length, line MB had to be multiplied by \frac{13}{9} to get 97.5

The reverse of this is dividing 97.5 by \frac{13}{9}:

97.5 ÷ \frac{9}{13} = 67.5

So x = 67.5

Mary had a link of yarn 4 1/3 inches long she cut it into two pieces for her art project one of the pieces was 2 1/2 inches long
GenaCL600 [577]

Answer: the length of the second piece is 1 5/6 inches

Step-by-step explanation:

Mary had a link of yarn 4 1/3 inches. Converting 4 1/3 inches to improper fraction, it becomes 13/3 inches.

She cut it into two pieces for her art project. One of the pieces was 2 1/2 inches long. Converting 2 1/2 inches to improper fraction, it becomes 5/2 inches.

Therefore, the length of the second piece would be

13/3 - 5/2 = (26 - 15)/6 = 11/6 inches.

Converting to mixed fraction, it becomes

1 5/6 inches
