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).

Hope its the correct answer
Given:
The discount is 25%.
The selling price of the shirt after the sale is $20.99.
To find:
The selling price of the shirt before the sl;e
Explanation:
Let the old price be x.
The equation can be framed as follows,
Final answer:
The selling price of the shirt before the sale is $27.99.
Answer:
-1/2 > x > -3
Step-by-step explanation:
i)
-2x+3>4
-2x> 1
x < -1/2
ii)
-2x+3<9
-2x<6
x > -3
= -1/2 > x > -3
I would get $19 back if I gave the clerk $40
An equation is an expression used to show the relationship between two or more variables and numbers.
Total money spent on book and CD = $12 + $9 = $21
The money gotten back = $40 - $21 = $19
I would get $19 back if I gave the clerk $40
