8-68.
Write down any observations or patterns you found while working on problem 8-67. For example, if the area of one shape is 100 times larger than the area of a similar shape, then what is the
ratio of the corresponding sides (also called the linear scale factor)? And if the linear scale factor is r, then how many times larger is the area of the new shape?

What is the slope simplify your answer and write it as a proper fraction, improper fraction, or integer

State whether weight is a function of height for the six students and explain. a. yes, height is a function of weight because two students weigh 165 pounds but have different heights. b. no, height is not a function of weight because two students weigh 165 pounds but have different heights. c. yes, weight is a function of height because for each value of height there is one corresponding value of weight. d. no, weight is not a function of height because there is not enough data to determine a function.

Solve for x -2.3(r - 1.2 ) = -9.66 enter you answer as decimal.
