Answer:
D. (7, 0)
Step-by-step explanation:
The rule for a reflection over the y-axis is (x, y) → (x, -y)
This means that the x-values stay the same while the y-values change.
Q(x, y) → (x, -y)
Q(3, 0) → (3, 0)
Q'(3, 0)
P(x, y) → (x, -y)
P(5, 6) → (5, -6)
P'(5, -6)
R(x, y) → (x, -y)
R(7, 0) → (7, 0)
R'(7, 0)
Therefore, the correct answer is D.

Answer:
2√3
Step-by-step explanation:
5y2+20=80
Step 1: Subtract 20 from both sides.
5y^2+20−20=80−20
5y^2=60
Step 2: Divide both sides by 5.
5y^2
/5 =
60/5
y2=12
Step 3: Take square root.
y=√12
y=2√3
Answer: x = -5
Step-by-step explanation:
First convert 3/4 to decimal= 0.75
0.75 (8x - 4) = 7x + 2
6x - 3 = 7x + 2
Transpose 7x from right hand side to the left hand side
6x - 7x = 2 + 3
-x = 5
x = -5
I hope this helps.
D is the answer
(4+8)+1 = 13
4+(8+1) = 13
Therefore equation D is true
