Nathan is playing golf at a golf course. the height of the golf ball from the ground, in feet, x seconds after the ball is hit is given by the expression below. what do the zeros of the expression represent? the times at which the golf ball reaches the maximum height the times at which the golf ball is on the ground the maximum height of the golf ball in the air the horizontal distance traveled by the golf ball

The times at which the golf ball is on the ground

at 0 seconds and 9 seconds

Step-by-step explanation:

answer: -1

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
