:
triangle def has coordinates d(2, 5); e(-1 5); f(1, 2). find the coordinates of the image d’e’f’ after a reflection across the y-axis. (2 points)

D' (-2,5), E' (1,5); and F' (-1,2)

Step by step explanation:

When one does a reflection across the y-axis, the values of the y-coordinate for the order pairs remain the same value, while the values of the x-coordinates flip their signs.

Therefore:

point D (2,5) becomes D' (-2,5)

point E (-1,5) becomes E' (1,5)

and point F (1,2) becomes F' (-1,2)

the f

last graph i believe

step-by-step explanation:

worked it out i believe

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).

hope i
