Consider the graph showing two functions. Which answer can be used to find the solution to the system of equations? A. x = 3/x
B. x = 9/x
C. 0 = 3/x + x
D. 0 = 9/x + x

b

Step-by-step explanation:

I think it is

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

answer: what are the following choices
