Which pair of equations represents two perpendicular lines?A. y=-7/8x+3 and -7y=-8x B. 8y=3x+40 and y=8/2x-1 C. 5y=15-2x and 2/5x-4=y D. y=9x+3 and y=9x-1/3
Answers
I am pretty sure that the answer is A. because the slopes are reciprocals of each other, and so they are perpendicular
47.44Cassidy wrote the linear equation y 5x+4 Then, she wrote the equation of the line that is parallel to y 5x+4and thatpasses through (8, 2). lf her new equation is in the formy 5x+ b, what is the value of b?Mark this and returnSave and ExitNextSubmit
Answers
y=mx+b m=slope paralell has same slope
point (8,-2) x=8 and y=-2 is a solution
sub those for x and y -2=5(8)+b -2=40+b minus 40 both sides -42=b
the value is -42
Raphael paid $652 for a camera during a 20% off sale. What was the camera's regular price? Please work the problem and show your work so I can understand it better.
Answers
The price the Rafael paid for the camera is 652 dollars which already has a discount which is 20%. There are a lot of ways to solve it, however, I'll show you the easiest way. => 652 dollars is the 80% of the price since it lessen by 20% => 652 / 8 = 81.5 is the 10% of the price. => 81.5 * 10 = 815 dollars is the original price of the camera.

What is the slope of the line whose equation is 2y=5Ć+4?
Answers
2y=5x+4
Transforms into:
y=5/2x+2
Therefore the slope is: 5/2
