Polynomial of lowest degree with zeros of 3/4 (multiplicity 2) and -3/5 (multiplicity 1) and with f(0) = -81

Step-by-step explanation:

f(x) = a (4x − 3)² (5x + 3)

-81 = a (0 − 3)² (0 + 3)

a = -3

f(x) = -3 (4x − 3)² (5x + 3)

the answer is d

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
