\begin{cases}
I=\textit{interest earned}\\

What are the coordinates of the image of vertex R after a reflection across the y-axis? (–4, 3) (4, –3) (–3, –4) (3, 4)
bogdanovich [222]

(–4, 3) (4, –3) (–3, –4) (3, 4)

this is a rather simple yet complex concept the easiest way to solve these is to do the exact opposite.

so in this instance it is refrcted across the y-axiss so we swap ONLY the x value NOT the Y ie (-4,3) would switch to (4,3)

same thing would apply if it reflected across x-axis ex (-4,-3)

If it reflect across orgin you change both signs. ex (4,-3)

ie.

(–4, 3) (4, –3) (–3, –4) (3, 4)

changes to

(4, 3) (-4, –3) (3, –4) (-3, 4)

hope it helps

If y=36 when x=6 find x when y=42
emmasim [6.3K]

Answer:

x = 7

Step-by-step explanation:

First, solve by dividing y with x

When x = 6, y = 36

36/6= 6

6(x) = y is your equation.

Now plug in 42 for y

6(x) = 42

Isolate the x. Divide 6 from both sides

(6x)/6 = (42)/6

x = 42/6

x = 7

7 is your answer for x.
