Solve this equation. 5n+7=7(n+1)-2n
Trava [24]
5n + 7 = 7(n+1) - 2n

First distribute 7 to all terms inside the parenthesis

7(n) = 7n
7(1) = 7

5n + 7 = 7n - 2n + 7

Simplify. Combine like terms

5n + 7 = 5n + 7

True.

If you want to continue:

Isolate the n, move all variables to one side, and constants to the other

5n (-5n) + 7 (-7) = 5n (-5n) + 7 (-7)

0 = 0

True


hope this helps

<u>Hello:</u>

<u />

<u>Okay, this problem should be taken in a series of steps</u>:

<u>What is the slope's formula?</u>

  \rm\hookrightarrow  \frac{y_2-y_1}{x_2-x_1}

  • (x₁,y₁) -- first point
  • (x₂,y₂) -- second point

<u>Okay, now let's use this knowledge</u>  

10. (5,-19) and (-5,21)

       Slope = \frac{21--19}{-5-5} =\frac{40}{-10}=-4

11. (12,1) and (12, -1)

      Slope = \frac{-1-1}{12-12} =\frac{-2}{0}

12. (8,7) and (4,7)

     Slope = \frac{7-7}{4-7} =0

<u>Answer:</u>

  • Question 10: -4
  • Question 11: undefined
  • Question 12: 0

Hopefully that helps!
