Which equation has the solution set x= {2,3}? a.2/3x=0 b.(x-2)(x-3)=0 c.(x+2)(x+3)=0 d.(2x+3)^2=0

B

(x - 2)(x - 3) = 0

To solve equate each of the factors to zero and solve for x

x - 2 = 0 ⇒ x = 2

x - 3 = 0 ⇒ x = 3

solution set is x∈ [2, 3]

note that (x + 2)(x + 3) = 0 has solution set x ∈[- 2, - 3]

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
