Answers
Answer:
The coordinates A(4,1),B(4,−1),D(−4,1) and C(−4,−1) are plotted to form a rectangle.
The rectangle so formed and the reflected rectangle is shown in figure.
It is reflected through x=5 then the coordinates of the new rectangle become

Answer:
x < 7.25
Step-by-step explanation:
We distribute 1/4 into the parenthesis to get
1/4-x > -7
Subtracting 1/4 from both sides gives us
-x > -7 1/4
We can simplify the RHS (Right Hand Side) leaving us with
-x > -7.25
Multiplying (or dividing) by -1 gives us
x < 7.25
Notice that we switch the sign due to the rule of multiplying or dividing by -1.
