Which of the following symmetries apply to the isosceles trapezoid below?

Reflective symmetry over the line y=-x

Step-by-step explanation:

This trapezoid is symmetrical around an axis defined by the line y=-x.

It is not, symmetric with an image of itself rotated by 90 degrees. Neither is it symmetric to an image obtained by reflection around -7x+1. These two statements can be easily verified by transforming one of its corner points and realizing they do not belong to the set of corners of the original trapezoid.

3.4 pizzas

step-by-step explanation:

given is a scatter plot showing number of pizzas sold during weeks for different issues of coupon

y represents number of pizzas sold and x number of coupons issued

y is marked verticaly and x horizontally

the trend line is given as

y =3.4x+43

this says that even when no coupon is issued pizzas sold will be 43

and rate of change of pizza sold for 1 unit of coupon = slope = 3.4

i.e. when x increases by 1 unit y increases by 3.4 units

hence for each additional coupon issued 3.4 pizzas more will be sold
