12. The graph of a linear function f passes through the points (4, w) and (r, 7) in the xy - plane and has a slope of
Which of the following is true?

A) r + w= 4/5
B)4r - 5w = 19
C) -9rw = 51
D) 4r + 5w = 51

no

Step-by-step explanation:

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
