Answer:

x=-7

Step-by-step explanation:

-(x-13)=10(x+9)

distribute the negative on the left side and the 10 on the right side

-x+13=10x+90

add x on both sides

13=11x+90

subtract 90 on both sides

-77=11x

divide 11 on both sides

-7=x

x=-7

Subtract 10x from both sides:

- x + 13 = 10x + 19

- x + 13 - 10x = 10x + 90 - 10x

- 11x + 13 = 10x + 90 - 10x

- 11x + 13 = 90
—————————————————-

Step 2: subtract 13 from both sides:

- 11x + 13 = 90

- 11x + 13 - 13 = 90 - 13

- 11x = 90 - 13

- 11x = 77
———————————————————

Step 3: divide both sides of the equation by -11:

- 11x = 77

- 11x/-11 = 77/-11

x = 77/-11

x = - 7
————————————————————
So the answer is x = -7

Hope this helped oh and can I have brainliest

Answer:

Step-by-step explanation:

4) (-2,3)   ;  (-1,-2)

Slope = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\=\frac{-2-3}{-1-[-2]}\\\\=\frac{-5}{-1+2}\\\\=\frac{-5}{1}\\\\=-5

5) line is parallel to x-axis. So, slope= 0

6) (1,1) ;  (-2, -1)

Slope=\frac{-1-1}{-2-1}\\\\=\frac{-2}{-3}\\\\=\frac{2}{3}
