Annie walks 15 feet away from her house and places a mirror on the ground. she backs 4 feet away from the mirror so that she can see the tip of the roof. annie's eyes are 5 feet above the ground. annie and the house are both perpendicular to the ground. the angles between the top of the house, the mirror, and the ground and between annie's eyes, the mirror, and the ground are congruent as shown in the image below:

when studying polynomials, you often hear the terms zeros, roots, factors and x x the multiplicity of a zero is important because it tells us how the graph of the let's look at the graph of a function that has the same zeros

step-by-step explanation:

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
