Answer:
D
Step-by-step explanation:
b-1≥ 0 or b-7<-8
b ≥ 1 or b<-8+7
b ≥ 1 or b<-1
21 times because you need 7/4=1 gallon and 3/4 just for one and 7x3 =21 so need 21/4
The answer is A

Step 2
To explain this as stated above line A and line B intersect each other at a right angle hence line A and B are perpendicular lines. The line segments are seen below.
