Solve y=x²+7 for x for apexvs homeschool 2019

Hello!

To solve for x means to isolate x:

y = x^2 + 7

y - 7 = x^2

sqrt(y - 7) = x

x = sqrt(y - 7)

Hope this helps if it did please make brainliest!

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
