Answer:

r = -45

Step-by-step explanation:

okay so to solve for r you have to isolate r

and in order to that you must use inverse operations, in this case you have to multiply since its the opposite of dividing

r/5 = -9

multiply both sides of the equal sign by 5 to isolate r

then you will get

r = -45

making -45 your answer

OUR GOAL: To isolate the variable "r" on one side...

1) Multiply both sides of the equation by 5 to get r on one side:

r=-9*5

2) Multiply:

r=-45

Find the slope of the line passing through (-7,-8) and (5,-8)
zhenek [66]

Answer:

slope = 0

Step-by-step explanation:

Calculate the slope m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 7, - 8) and (x₂, y₂ ) = (5, - 8)

m = \frac{-8+8}{5+7} = \frac{0}{12} = 0

Novay_Z [31]

Answer:

Option C.

Step-by-step explanation:

By the property of unique triangles (ASA), one side is included between the two angles.

By this property, if included side of the triangle ABC is AB then this side will be included between the two angles A and B.

Therefore, \bar{AB} is included between ∠A and ∠B.

Option C. will be the answer.
