Answer:
<em>(6,3), last option</em>
Step-by-step explanation:
<u>Symmetry To A vertical line</u>
If the point Q (unknown) is symmetric to point P(2,3) with respect to x=4, it means it's located at the same distance to the line as P while keeping the same y-coordinate.
The point P has a distance of 4-2=2 units with respect to x=4. Q must have its x coordinate equal to 4+2=6, and keeping the y-coordinate equal to 3
The coordinates of Q are (6,3), last option
Answer:

Step-by-step explanation:
we know that
The expression Subtract
from
is equivalent to the algebraic equation


Group terms that contain the same variable
Combine like terms



If the y-intercept is at -69, meaning the point is (0, -69), thus x = 0, y = -69
Answer: B) Addition Property
Step-by-step explanation:
The Step 3 is: 
The idea is to solve the equation, which means that you have to find the value of the variable
.
As
is a subtraction, you need to add 30 to both sides of the equation to keep the equation balanced. This property is known as "Addition property of equality".
This property states that adding the same number to both sides of the equation, the equality does not change:

Then, the Addition property of equality applied in Step 3, get you to Step 4:
