Graph A
Step-by-step explanation:

Its mean graph should intersect x axis at x = 7 and x = - 1. This everything is satisfied by graph A.
Answer:
subtract 7 from both sides
2x < 7- 7
subtract 7 from 7 to get 0
2x < 0
product of two numbers is < 0 if one is > 0 and the other is < 0. since 2> 0, must be < 0.
x < 0
