It's #25 guys. Show your work!
Ronch [10]
y+8 = \frac{1}{2}(x-7) is equivalent to <span>y-(-8) = \frac{1}{2}(x-7)

That is in the form </span><span>y-y_{1} = m(x-x_{1}) which is point slope form

In this case,

m = 1/2 is the slope
(x1,y1) = (7,-8) is the point the line goes through</span>

Solve the following equation, answer as a reduced, mixed number. Then place the correct number in the box provided.
stira [4]

Answer:

The answer to your question is:   x = - 1 / 8

Step-by-step explanation:

                                           8( 1 - 5x ) = 13

                                            8 - 40x = 13

                                             - 40x = 13 - 8

                                             - 40x = 5

                                               x = - 5 / 40

                                               x = - 1 / 8
