What is the equation of the line that is perpendicular to the line y=}x+10 and passes through the point (15,-5)? -x+
V
O y=xx-20
O y=-3x +20
Ov=x-20
O y=-x+20

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

pretty sure 750 each month!
