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
Answer from: Quest
The answer will be y=-5+0 because the slope is -5 and the it has to go through y-axis 0
Answer from: Quest
y=3x+4
step-by-step explanation:
given the points a(0,4) and b(-4, -8)
eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)
(y-4)/x=-12/-4=3
y=3x+4

Aman is 6 feet 3 inches tall. the top of his shadow touches a fire hydrant that is 13 feet 6 inches away. what is the angle of elevation from the base of the fire hydrant to the top of the man's head?
One of the complementary angles is 4 degrees mor than the other. find the angles (recall that complementary angles are angles whose sum is 90 degrees.) which of the following can not be used to solve the problem if x represents one of the angles? a. 2x-4=90 b. 2x+4=90 c. x+4=90
