An asteroid was discovered. It is estimated to have a mass of 2.14 x 1021 kg and is moving at a speed of 17,900 m/s. What is the amount of kinetic energy found in this asteroid?

c. (3,2,6) is the answer.

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

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
