Tell whether the lines for each pair of equations are parallel, perpendicular, or neither. y=-2x+4 -5x+10y=5 a: parallel b: perpendicular c: neither

y=-2x+4

the slope is -2

-5x+10y=5

solve for y

add 5x to each side

10 y = 5x+5

divide by 10

y = 1/2 x +1/2

the slope is 1/2

take the negative reciprocal of -2

- (1/-2) = 1/2

The two lines are perpendicular

step-by-step explanation:

ok one would be money, and the other would be refreshments or something similar. if each bag of popcorn is 5.00 and each drink is half of that that means drinks are 2.50 the proper way to do that would to look and see how much of each you can buy without exceeding a limit of 30.00
