For this case we have the following situation:
The monthly cost of a gym in the city is $ 3. The initial registration is $ 25. Write a mathematical expression that models the problem.
So we have to define variables:
x: number of months
y: total cost
The mathematical expression that models the problem is:
I think it's the first 7.
I hope this helps :-)
Answer:
D. (-9)+9=0
Step-by-step explanation:
Additive inverse means that the sum of the original number and its Additive inverse must add upto 0. In this case, if we add -9 and 9 then we get 0. That's why D is the correct answer.
The angles have to have a 90 degree angle , and they have to be equal too
1. y=7/8x +1
2. y=-10x
3. y=2.5x-7
4. y=1.2x
5. y=-5x-8
