Determine whether the lines y = 4x and y = 2x are parallel, perpendicular, intersecting, or coinciding.

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.
