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:
Afful is 21 and Naomi is 13.
Step-by-step explanation:
Let
represent the age of Afful and
represent the age of Naomi.
The sum of their ages is 34. In other words:

In 5 years time, Afful will be two times the age of Naomi <em>now</em>. In other words:

Solve for the system. Substitute.

Afful is currently 21 and Noami is currently 13.
(35-21) = 14 so your answer would be 14
(7/6 x 30= 35 and 7/6 x 18= 22
65.0
This is because 4 is not a big enough number to round up, so you must round down. When it is 5 and over, you can round up.
