Okay, since you haven't given us all the information needed, I'll explain what you need to do instead.
First, you need to find the value of x. This will either be listed somewhere in the directions, or in the remainder of the question.
Once you find the value of x, you see how many times x will go into 8.
For example, say x is equal to 2.
8 divided by 2 = 4 and/or 2 goes into 8 four times.
I only know the answer for b I don't know the answer for d. So here is the answer for b 9 time 9= to 18+11+8x4-1=60
Answer: 1/4x
The slope of the line in the graph is -4x so the negative reciprocal of that is 1/4x. Hope this helps! :)
X is the number
sum means add
sum of half a number and 4 means
(x/2)+4
result is -16
(x/2)+4=-16
minus 4 both sides
x/2=-20
times 2 both sides
x=-40
the number is -40
