Vivian is at a fair in coachella valley, california. much of the valley lies below sea level. vivian has brought along an altimeter to measure her elevation at different places in the valley. vivian's first ride was on the ferris wheel. when she sat on the wheel at its lowest point, her altimeter read -9.6 feet. when she reached the top of the wheel, her altimeter read 12.3 feet.

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

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.

i believe that the slope of the line is -5
