10. The coordinate point P (-4,5) is one of the vertices of a pentagon. If that pentagon is rotated 90° counter clockwise, what would its new coordinate be?
A. (-5, 4)
B. (-5,-4)
C. (4,5)
D. (5,4)

idk

step-by-step explanation: i just don't

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

b. f(x) = –√x + 3this is the correct answer
