4 weeks
Step-by-step explanation:
14.50 (4) + 20= 78
12.50 (4) + 28= 78
The equation of a line can be expressed in slope intercept form as y = mx + b where m is the slope and b is the y-intercept. Horizontal lines have a slope of 0, so the equation is simply y=b.
The y value of the point given is -5, so the answer is y = -5.
Answer:
16 feet
Step-by-step explanation:
As said in the problem statement, the angles between the top of the house, the mirror, and the ground and between Sarah's eyes, the mirror, and the ground are congruent.
We also know that Sarah and the house are perpendicular to the ground.
So if we draw a triangle from the top of the house, to the mirror, to the bottom of the house, and another triangle from Sarah's eyes, to the mirror, to Sarah's feet, we get two triangles that have the same angles. Therefore, the triangles are similar, and we can write a proportion:
4 / 5 = h / 20
h = 16
The house is 16 feet tall.
They look yo be all functions due to them not intersecting one another
