Answer:
B. 
Step-by-step explanation:
I graphed this function on the graph below and it matched the graph you have.
7/10 - 1/4 use common denominators
28/40 - 10/40 = 18/40 = 9/20
To solve this inequality, you need to isolate the value of u. To do this, divide both sides by -2. When you do this, keep in mind that when you divide or multiply both sides by a negative in an inequality, you MUST flip the sign, so your answer would be -8 < u or u > -8.
