Answer:
A' ( 2, 4) and B' ( -4, 0)
Step-by-step explanation:
A ( -2, 4) and B( 4,0) reflected over the y-axis
A' ( 2, 4) and B' ( -4, 0)
the y-coordinate do not change and the x is opposite sign
(x,y) reflected over y-axis (-x, y)
Use the pythagorean theorem:
EF² +DF²=DE²
EF²=18²-12²=180
EF=√180
E is the answer.
Answer:
No
Step-by-step explanation:
In order for it to be a function, every input (x values on the left) needs to be paired with only 1 output (y values on the right). Notice that 1 is paired with both 2 and 4. This means it is not a function, but it is paired with two different values.
ANSWER:
STEP-BY-STEP EXPLANATION:
We have the following expression
In this case, the exponents are subtracted since it is a division, therefore we would have:
Answer:
B.) Reflection over y=-3
