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).
Let's solve for x.

Answer:
4250
Step-by-step explanation:
5000 packs of gum were produced by the factory.
85% of them contained mint-flavoured gum.
That is,
(85/ 100) × 5000 packs contained mint-flavoured gum.
= 85 × 50
= 4250.
Answer:
Out of 5000 packs, 4250 contained mint-flavored gum.
