b is the correct answer
Step-by-step explanation:
see the step in the picture
Find 2 coordinates on the graph : (0, -20) and (10, 10)
Slope = (10 - (-20) ) / (10 - 0) = 30/10 = 3
Slope = 3
y-intercept = (0, - 20)
Equation : y = 3x - 20
Since the right hand side is shaded, the equation is y > 3x - 20.
The answer is d, 65.1. 18.6•3.5=65.1
Answer: $3.92
STEOS TO SOLUTION: take $19.62 and divide by 5
