3 Fill in the Blank 3points Explain what you know about the images that result from translating, reflecting and rotating the same pre-Image. The images that result from the same pre-image are square disappointed to eachother and to the pre-image. When you perform a rigid motion, you square v size and shape, so the measures all square v

Consider this diagram and answer the questions that follow: The marked angles are supplementary The marked angles are corresponding. B The marked angles are not equal. The marked angles are equal. D The marked angles are conseculve interiot His marked angles are alternate interiot Is there a pair of parallel lines in the diagram? $\square $ Yes No
8 One or more of your responses is incorrect. Recall that the slope of a line m is found using two points on the line and the equation $m=\frac {y_{2}-y_{1}}{x_{2}-x_{1}}$ Review how the slopes of parallel lines are related.
According to a health statistics center, the mean weight of a 20-10-29-year-old female is 156.5 pounds, with a standard deviation of 512 pounds, The mean weight of a 20-to 29-year-old male is 183.4 pounds, with a standard deviation of 40 O pounds. Who is relatively heavier: a 20-10-29 -year-old fomale who weighs 160 pounds or a 20-to-29-year-old male who weighs 185 pounds? The 2-score for the female is $\square $ . The z-scare for the male is $\square $ Thus, the $\square $ is relativoly heavier. (Round to two decimal places as needed.)
c) Determine $1(-x)$ and simplify. $f(-x)=\square $ (Simplify your answer. Do not factor.)
