The dilation of one of the distances from the origin to one of the endpoints of each triangle was from 8 to 3.2, since we add the lengths. Therefore, the scale factor was 3.2/8 = 2/5
Answer:
y = (x +2)(x -1)(x -3)
Step-by-step explanation:
For each x-intercept (r) the corresponding factor is (x -r). For x-intercepts -2, 1, 3, the factors are ... (x+2), (x-1), (x-3). Then the equation is ...
y = (x +2)(x -1)(x -3)
Answer: see image
<u>Step-by-step explanation:</u>
Draw the line y = 1. Count how many units away the point is from that line. Move that point the same number of units in the opposite direction to create the reflection.
J is 2 units above y = 1. The new point is 2 units below y = 1. → (3, -1)
K is 3 units above y = 1. The new point is 3 units below y = 1. → (6, -2)
L is 5 units above y = 1. The new point is 5 units below y = 1. → (3, -4)
M is 3 units above y = 1. The new point is 3 units below y = 1. → (0, -2)
Stefanie swam 1/3 further in the morning.
4/5 - 7/15
12/15 - 7/15 = 5/15
5/15 = 1/3
