Let f(x) = 3x - 8 and g(x) = 2x2. Find f(g(5))

Step-by-step explanation:

f(x)=3x-8

g(x)=2x^2

f(g(5))=f(2×5^2)

=f(50)

=3×50-8

=150-8

=142

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
