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).
4³/₄ pints
<h3>Further explanation</h3><u>Given:</u>
A-Plus auto body is painting desigs on a customer's car.
<u>Question:</u>
How many more pints of blue paint will they need?
<u>The Process:</u>
From the denominators 2 and 3 above, we get LCM = 6.
Let us draw a diagram that contains all the pints.
The flames: or half of 6 unit above, that is
The sparks: or 2 of 6 unit above, that is
So, the remainder is 18 - 9 - 6 = 3 pints.
They needed pints of blue paint to paint the next design.
Let us count how many more pints of blue paint will they need.
Thus, they pints more of blue paint.
