loris [4]3 years ago

Answer:

A. \frac{3 - 7}{-4 -(-7)} = \frac{-5 - 3}{2 - (-4)}

Step-by-step explanation:

Slope of PR = \frac{y_2 - y_1}{x_2 - x_1}

Where,

P(-7, 7) = (x_1, y_1)

R(-4, 3) = (x_2, y_2)

Slope of PR = \frac{3 - 7}{-4 -(-7)}

Slope of RT = \frac{y_2 - y_1}{x_2 - x_1}

Where,

R(-4, 3) = (x_1, y_1)

T(2, -5) = (x_2, y_2)

Slope of RT = \frac{-5 - 3}{2 - (-4)}

Therefore, the proportion that can be used to show that the slope of PR = the slope of RT is:

\frac{3 - 7}{-4 -(-7)} = \frac{-5 - 3}{2 - (-4)}

A 6500 gallon storage tank is 2/13 full of oil. How many gallons of oil are in the tank
user100 [1]

The gallons of oil in the tank is 1000

A 6500 gallon storage tank is 2/13 full

The number of oil in the tank can be calculated by multiplying the amount of gallons in the tank which is 6500 by the measurement of the tank which is 2/13

= 2/13 × 6500

= 13,000/13

= 1,000

Hence 1000 gallons of oil are in the tank

Points A, B, and C are collinear. Point B is between A and C. BC=8x+709. AB=487+5x. AC=91. Find BC.
Zolol [24]

Answer:

<h3>            BC = 29</h3>

Step-by-step explanation:

Point B is between A and C and the points A, B, and C are collinear so:

AB + BC = AC

487 + 5x + 8x + 709 = 91

  13x + 1196 = 91

       - 1196      - 1196

   13x  =  - 1105

     ÷13     ÷13

    x = - 85

BC =  8x + 709 = 8(-85) + 709 = - 680 + 709 = 29
