Answer:
Option 3: 
Graph C
Step-by-step explanation:
Find the solution of 

(multiplication property of equality)
Divide both sides by -1. Since we are dividing by a negative number, the sign would change

This means that the possible values of x are 8 and any number above 8.
Graphing this, the arrow of directed line would start at 8 and move towards our right hand.
Thus, the graph would be graph C in option C.
Answer:
490kpa
Step-by-step explanation:
V1 = 70ml and P1 = ? kpa
V2 = 15ml and P2 = 105kpa
if 15ml will give me 105kpa
then how many times is 70ml greater than 15ml
70/15 = 4.6667
then multiply it by 105kpa
4.6667 * 105 = 490kpa
meaning that if 15ml will give me 105kpa
then 70ml which is (15*4.667) will give 490kpa
