Answer: "always" for both
A line segment is <u>always</u> similar to another line segment, because we can <u>always</u> map one onto the other using only dilations and rigid transformations.
==================================
Explanation:
A dilation is where we grow or shrink an object. In this case, it would be lengthening or shortening a line. We can dilate any line to get it to any desired length we want. Then to make sure it matches up perfectly with the other line, we can perform translations (aka shifting) and rotations.
In other words, if we have four points A,B,C,D then it is possible to use dilations and rigid transformations to map points A,B to points C,D. The first segment AB would map to segment CD.

Answer:
Y/X=
172.50/23=
7.50/1
Step-by-step explanation:
Answer:
a. C=20x + 44 where C is total cost, and x is the number of months.
b. $164
Step-by-step explanation:
Where C is total cost, and x is the number of months, we get the equation
C=20x + 44
the 20 is the monthly fee and the 44 is the initial membership fee which is only paid once.
To get the answer for b plug in 6 as the x. The equation gives you the answer $164.
Average change would be : -24/6
simplified, would be : -4......so the temperature changed -4 degrees every week for 6 weeks
