The sum of twice a number and 5 is at most 3 less than the number
Rasek [7]

So this is our inequality in algebraic terms: 2n+5\leq n-3

What is -6(-3+5r)=-5-7r
inna [77]

Answer:

r = 1

Step-by-step explanation:

Use the distributive property to multiply −6 by −3+5r.

18−30r=−5−7r

Add 7r to both sides.

18−30r+7r=−5

Add −30r and 7r to get −23r.

18−23r=−5

Subtract 18 from both sides.

−23r=−5−18

Subtract 18 from −5 to get −23.

−23r=−23

Divide both sides by −23.

r=−23/−23​

Divide −23 by −23 to get 1.

r=1

  m = (1 -8)/(-2 -(-8)) = -7/6

The slope of the line is -7/6.
