Answer:

y = -0.8x - 5

Step-by-step explanation:

x1 = (XA + XB) / 2 = -5

y1 = (YA + YB) / 2 = -1

m = (XA - XB) / (YA - YB) = -0

__________________________________________

(y - -1) = -0.8(x - -5)

y - -1 = -0.8x - 4

y = -0.8x - 4 + -1

y = -0.8x - 5

Simplify into one fraction -5 / x - 3 - -4 / x + 2
slamgirl [31]
To simplify the expression we shall have:
-5/(x-3)--4/(x+2)
=-5/(x-3)+4/(x+2)
putting the fraction under the same denominator
[-5(x+2)+4(x-3)]/[(x-3)(x+2)]
=[-5x-10+4x-12]/[(x-3)(x+2)]
=[-x-22]/[(x-3)(x+2)]
Answer: 
[-x-22]/[(x-3)(x+2)]

9x-23=49 what is the second step in this equation?
ladessa [460]

Answer:

Divide both sides by 9.

Step-by-step explanation:

To find the second step of the equation, we actually have to solve parts of the equation until we get to step 2.

Step 1: Add 23 to both sides.

  • 9x - 23 + 23 = 49 + 23
  • 9x = 72

Step 2: Divide both sides by 9.

  • \frac{9x}{9} = \frac{72}{9}
  • x = 8

Therefore, the second step is divide both sides by 9.

Have a lovely rest of your day/night, and good luck with your assignments! ♡
