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).

Answer:
The length of the tunnel is 7.66667 inch
Step-by-step explanation:
We are given
1 inch =60 miles
now, we can find for 1 mile
so,
60 miles = 1 inch
we get
we are given
total length is 460 miles
so, we can multiply both sides by 460
now, we can simplify it
So,
The length of the tunnel is 7.66667 inch
The answer can be found by squaring 6 which gives you 36 minus 30 because negative 5 times 6 is negative 30 so it would be 36-30-3 which is 3
