The function a(b) relates the area of a trapezoid with a given height of 10 and one base length of 7 with the length of its other base. it takes as input the other base value, and returns as output the area of the trapezoid. which equation below represents the inverse function b(a), which takes the trapezoid's area as input and returns as output the length of the other base?

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
