Answer:

x = 7 and x = -1

Step-by-step explanation:

<u>Step 1:  Factor</u>

x^2 - 6x - 7 = 0

(x - 7)(x + 1) = 0

<u>Step 2:  Solve for x</u>

(x - 7)(x + 1) = 0

x - 7 = 0 and x + 1 = 0

x - 7 + 7 = 0 + 7 and x + 1 - 1 = 0 - 1

x = 7 and x = -1

Answer:  x = 7 and x = -1

  y -k = m(x -h) . . . . . line with slope m through point (h, k)

You find that k = -5, m = 1/2, h = -12.

How would you find the value of x is x equals five, in the equation...5x+29=45?
gavmur [86]
5x+29 = 45
5x = 16 (subtract 29 from both sides)
x = 16/5.

That is the answer, I don't know where you got the value of 5 but it doesn't make sense. To prove it, let's try put it into the equation:

5x5 + 29 =45
25 + 29 = 45
Wrong! 25 + 29 = 54.
