<h2>B. -12x^3 + 28x^2<= your answer</h2>
C. -12x^3 − 28
D. -12x^3 − 28x^2
It would take 20 hours
300/15= 20
Answer:
80
Step-by-step explanation:
first add the parenthesis (9+7) = 16
then multiply 16 * 5 = 80
Y=-2 is a horizontal straight line. The perpendicular line is going to be a vertical line (x=). Since it is vertical with no range, the line is a y-output of all numbers at any x input. So for the line to get to (4, -2) the x would need to be at 4, making the perpendicular line x=4
