A line is drawn on a coordinate grid by the equation x = 5. Which of the following lines would represent a row perpendicular to it? A. a line containing the point (5,2)
B. y = 5
C. x = 5
D. x = 3

y=5

Step-by-step explanation:

Perpendicular means what will make a 90 degree angle off of it. We know that the line is X=5, which is a vertical line. Y=5 is a horizontal line. So when you have a vertical line, then put a horizontal line through it, you will get a 90 degree angle, meaning it is perpendicular.

5x+2x=49

7x=49

x=7. 35 apples

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50
