Use the zero product property to find the solutions to the equation 2x2 + x – 1 = 2.
a) x = -(1/2) or x = 2
b) x = –2 or x = 1/2
c) x = -(3/2) or x = 1
d) x = 1 or x = 3/2

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
