Answer:


Step-by-step explanation:
Standard form of a sideways parabola: 
Given equation:

Add x to both sides:


--------------------------------------------------------------------------------------------
<u>Standard form of circle equation</u>

(where (a,b) is the center and r is the radius)
Given equation:

Group like terms:

Divide by 2:

Factor by completing the square for each variable:

Rearrange into standard form:

Therefore, the circle has a center at (4.5, 2.5) and a radius of √23
Yes it’s true he has a 39% for each service
D. (?1, ?5) because it is only reflected across the x-axis, so it only effects the Y coordinates.
The ratio of the circumference to the diameter is defined as pi
pi=circumference/diameter
that is how they got pi
in this question it woul be 15.7/5 which would be 3.14,
c=2pir
a=pir^2
c=2pir=16pi
divide both sides by 2pi
r=8
a=pir^2
a=pi8^2
a=pi64
a=64pi in²
3x - 1 = 3x + 1
subtract 3x from both sides to get (-1 = 1). This is a false statement so it is: CONTRADICTION
************************************************
4x - 11 = 7
add 11 to both sides and then divide both sides by 4 to get
. This statement is true only when x =
so it is: CONDITIONAL
*************************************************
2 - 8x = 2 - 8x
add 8x to both sides to get (2 = 2). This is a true statement so it is: IDENTITY
*************************************************
x + 1 = -x + 4
add x to both sides, subtract 1 from both sides, and divide both sides by 2 to get
. This statement is true only when x =
so it is: CONDITIONAL
Answer: B, A, C, A
