Triangle abc and triangle deg are similar right triangles. which proportion can be used to show that the slope of ac is equal to the slope of dg? a) 4 − (−7) / 0 − 4 = −1 − 10 / 4 − 8b) −4 − (−7) / 0 − 4= 4 − 8 / −1 − (−10)c) 0 − 4 / −4 − (−7) = −1 − (−10) / −4 − 8d) 0 − 4 / −4 − (−7) = −4 − 8 / −1 − (−10)

the answer

b. they are parallel and will never intersect.

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
