Given:
The vertices of a triangle are R(3, 7), S(-5, -2), and T(3, -5).
To find:
The vertices of the triangle after a reflection over x = -3 and plot the triangle and its image on the graph.
Solution:
If a figure reflected across the line x=a, then
The triangle after a reflection over x = -3. So, the rule of reflection is
The vertices of triangle after reflection are
Similarly,
And,
Therefore, the vertices of triangle after reflection over x=-3 are R'(-9,7), S'(-1,-2) and T'(-3,-5).
Hey there!!

is a rational number as it has a definite answer 7.
Hope it helps you.
Answer:
Option B
Step-by-step explanation:
Average rate of change of a function 'f' in the interval x = a and x = b is given by,
Average rate of change of change =
Given function is,
g(x) =
We have to calculate the rate of change in the interval [-4, 3],
Average rate of change =
g(3) =
= 2.5 + 1
= 3.5
g(-4) =
= -1 + 1
= 0
Average rate of change =
=
=
Therefore, Option B will be the answer.
