Can I have the rest of the question(picture)?
Answer:
30
Step-by-step explanation:
x + 23 = ?
x = 7
All we need to do is plug in x =7 to the first equation:
7 + 23 = ?
We simplify and get:
30 = ?

Step-by-step explanation:
From the question we are told that:
Data
Generally the equation for Point estimate 
is mathematically given by
Answer:
All points on line x+y = 0 or x-y=0 will satisfy the transformation.
Step-by-step explanation:
Let (x, y) be the general such point.
Hence rotating it by 180 deg. counterclockwise will give us (-y,-x).
Reflecting (-y,-x) on x axis gives us (-y,x).
Hence if (x,y) = (-y,x) then all ( x, y) where x = -y or x+y = 0 or x=y or x-y=0 will satisfy this condition.
All points on line x+y = 0 or x-y=0 will satisfy the transformation.
