Jessica’s parents own a restaurant. During holidays, the restaurant serves large groups of people. At these times, Jessica helps her parents by serving food and refilling drinks. She makes $4.50 per hour and 10% of a $140 dollar tip for each group that is served. Jessica receives $25.25 at the end of a night when one group is served. Leth represent the number of hours Jessica worked. Write an equation that could be used to determine how many hours Jessica worked that night.

the answer is 8

step-by-step explanation:

3.14 x 8x8

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.
