Mr. Smyth uses the function L(x)= 2x^2 to determine the length, in feet, of his landscaping projects. He uses the function W(x) = 5x-2 to determine the width, in feet, of each project. Which function could Mr. Smyth use to determine the price, P(x), for a rectangular project if he charges $20 per square foot?

7 9/10 as an improper fractions is 79/10.

hope it : )

question says to graph a triangle (xyz) and reflect it over the line y=x to create triangle x'y'z'.

we know that line y=x has both coordinates equal like (1,1), (5,5) etc so we can easily graph that reflecting line.

description of transformation:

we can see that x and y coordinate gets switched after transformation like (2,8) changed to (8,2)

what do you notice about the two line segments you drew:

we see that line segments xp and x'p are of same length and perpendicular to the reflecting line y=x.

do you think you would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line? :

yes, i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line.

how do you know? :

by measuring the length of yk and y'k.
