Solve the equation of the function for n.
a(n) = 3n - 20
a = 3n - 20
a + 20 = 3n
(a + 20)/3 = n
n = (a + 20)/3
n(a) = (a + 20)/3
Answer:
C. (x, y) → (x, -y)
Step-by-step explanation:
The algebraic representation that correctly describes a reflection over the x-axis is (x, y) → (x, -y)
Here's an example to show understanding
Plot A is (4,6) and the reflection over the x-axis would be (4,-6)
I think the answer is 8. After solving i got 8
To find the area multiply the length by the width.
The length and width of a square are the same.
Area = 15 x 15 = 225 square feet.
