Find the distance between the points.
(7,9) and (-1,9)

The distance is 8 between (7,9) and (-1,9)

Step-by-step explanation:

For:

(X1, Y1) = (7, 9)

(X2, Y2) = (-1, 9)

d=(−1−7)2+(9−9)2√

d=(−8)2+(0)2√

d=64+0√

d=6–√4

d=8

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
