Answers
Answer from: cici65360
x=2
Step-by-step explanation:
f(x)=7-4x+x2
f(x) = x² - 4x +7
a=1 and b= - 4 and c= 7
the axis of symmetry is the line for equation : x = - b/2a
x = -(-4)/2 =2

Answer from: Quest
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
