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).

Notes: Two negatives make a positive. When you have an odd exponent of an negative number, you get a negactive result.
2-(-8)+(-2)³

Answer:

Step-by-step explanation:
First, we need to add the two fractions together. To do this we need to make the denominator a factor of both 8 and 5. Easy way to do this is to multiply each fraction by the denominator of the other fraction:



We can also show 2 brownies as
or 
Now we can subtract the two:

Simplify the fraction down by dividing by two:

Which is the fraction of brownie left!
