Step-by-step explanation:
The answer is letter B. Negative and Negative is Positive.
Answer:
3 because when x=2 the lines are at y 1 and 3, but the y 1 isn't shaded, so the answer is 3
we are supposed to explain
Which situation could be solved using the equation 
As we can see in the given equation , one number is -4 and the other number is 4
When we add two number of same value but opposite in sign we get zero.
This equivalent to the real life situation of paying a post paid bills.
Suppose you are using a post paid service , and the bills gets generated at the end of the month.
Suppose the bills amount is $x.
Once you pay that bills , then total outstanding again becomes $0.
Because 
4(c-d) is the answer bc the difference of (c-d) is done first, then multiplied by 4
.5 -(-7) would be just 7 because of the imaginary -1 it’s being multiplied 7+1+3-7=11 then divide
