56 = −8d + 8 there's not multiple answers
ollegr [7]

Answer:

d= -6

Step-by-step explanation:

56 = -8d + 8

1) You want to get d by itself. Subtract 8 from both sides.

56 = -8d + 8

- 8           - 8

<em>(8 - 8 = 0, and 56 - 8 is 48.)</em>

48 = -8d

2) Then, you divide my -8 on both sides.

(<em>48 / -8 is -6, and -8d / -8 is just d.)</em>

-6 = d

So, d = -6

These problems really aren't hard just set them equal to each other and see if what they are saying is true. Are they equal? Do they both equal 0?

Find the slope of the point, and reduce the lowest terms (7,3)(9,3)
Umnica [9.8K]
A point doesn't have a slope. A line has. You need to find the slope of the line that these 2 points are on. The slope is


(the difference of the 'y' values) divided by (the difference of the 'x' values)


That appears to be zero. It's a horizontal line.
