Answer: c) B' = (6, -3)
<u>Step-by-step explanation:</u>
The simplest way is to rotate the graph.
Rotating the graph 1 time to the left (counterclockwise) = 90°
Rotating the graph 2 times to the left (counterclockwise) = 180°
Rotating the graph 3 times to the left (counterclockwise) = 270°
The longer way is to reflect over the x-axis and over the y-axis, which is the same as a rotation of 180°
Z = (x, y) → Z' = (-x, -y)
<em>the image below shows the graph rotated 2 times = 180°</em>

In other words,
b > 3 & 2/15
or
========================================================
Explanation:
Let's convert the mixed number 2 & 3/5 into an improper fraction.
We'll use the rule
a & b/c = (a*c + b)/c
In this case, a = 2, b = 3, c = 5
So,
a & b/c = (a*c + b)/c
2 & 3/5 = (2*5 + 3)/5
2 & 3/5 = (10 + 3)/5
2 & 3/5 = 13/5
The inequality is the same as
---------------------
Let's multiply both sides by 15 to clear out the fractions
---------------------
Now isolate the variable b
Side note: Another way to go from 47/15 to 3 & 2/15 is to notice how
47/15 = 3 remainder 2
The 3 is the whole part while 2 helps form the fractional part. The denominator stays at 15 the whole time.
