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:24
Step-by-step explanation:
1 divided by 5=.2
120 times .2=24
C. 10x^2y + 6y^3
Due to you have two sides of 5x^2y and two sides of 3y^3
