Answer:
Step-by-step explanation:

This means a graph with a slope of -1, and a y-intercept of -3
question 3 = $150 because 50% is one half of 100% so 300/2 = 150
Answer is D.
x = 0 and x = 4
---------------
x + 17 ≥ -3
Isolate the x. Subtract 17 from both sides
x + 17 (-17) ≥ - 3 (-17)
x ≥ -3 - 17
x ≥ -20
----------------------------------------------------------------------------------------------------------------
x ≥ -20 is your answer
