Answer:
-8
Step-by-step explanation:
-31 and +31 cancel each other out leaving you with -8
5 - 5b < 1 - 4b
5 < 1 + b
4 < b
1 - 4b < 6 - 5b
1 + b < 6
b < 5
4 < b < 5
(The second less than sign is less than or equal to)

Here we have the following expression:
What we need to do is to substitute 
into our expression. Therefore:
Finally, when evaluating into the expression the result is 4.
Answer:
-5/8
Step-by-step explanation:
Step 1: Find the slope of line d. As we move from point (5, 2) to point (10, 10), x increases by 5 and y increases by 8. Thus, the slope of line d is
m = rise / run = 8/5.
Step 2: Find the negative reciprocal of this m = 8/5. Doing so will give us the slope of line e or of any other line perpendicular to line d:
Slope of line e: -(5/8) = -5/8
