The x-coordinate of the vertex can be found by -b/2a where the equation is ax^2 + bx + c
3x^2 + 6x + 3
b is 6, and a is 3
-b/2a = -6/2(3) = -6/6 = -1
The x-coordinate of the vertex is -1. To find the y-coordinate plug the x-coordinate into the equation and solve for y.
f(-1) = 3(-1)^2 + 6(-1) + 3
= 3(1) - 6 + 3
= 3 - 6 + 3
= 0
The y-coordinate is 0
The vertex is (-1, 0)

Answer:
B(5, 4)
Step-by-step explanation:
The midpoint formula is ...
M = (A +B)/2
Solving for B gives ...
B = 2M -A
B = 2(1, -2) -(-3, -8) = (2+3, -4+8) = (5, 4)
The coordinates of B are (5, 4).
Answer:
a because a variable cannot be a variable
Answer:
Explanation:
The expression that must be rewritten as a fully simplified fraction is:
You must, first, convert 
as a fraction.
The line over the decimal 4 means that the digit 4 repeats indefinetly.
To find the fraction that represents this number you follow this procedure:
Now, you can mutiply both fractions:
