You can find slope by doing the change in y over the change in x.

So if you have (3,-1) and (-2,-5) you do:

-1-(-5) / 3-(-2) =

-1 +5 / 3 + 2 =

a). 4/5

a. 4/5 because

the equation to find slope is

y2-y1 divided by x2-x1

which is -5-(-1) divided by -2-3 which is -4/-5 which is 4/5.

Solve the inequality: –3(x + 2) > 4x + 5(x – 7)
Gwar [14]

Answer:

29/12 > x

Step-by-step explanation:

–3(x + 2) > 4x + 5(x – 7)

Distribute

-3x -6 > 4x +5x-35

Combine like terms

-3x-6 > 9x -35

Add 3x to each side

-3x+3x-6 > 9x+3x -35

-6 > 12x-35

Add 35 to each side

-6+35 > 12x -35+35

29 > 12x

Divide each side by 12

29/12 > 12x/12

29/12 > x
