Answer:
X=16
Step-by-step explanation:

16-9 = 7
3X7= 21
Hope this help if you need help graphing I would use desmos

c is is the answer how much you going to have to graphic
1 would be D.
2. Is A since 3^2=9 and -3^2=9 And 9-9=0. Im pretty sure A. For number 3. Just because the two x-values are 3 and -3. I’m sorry if I’m wrong on #3.
