Answer:
x = 21.6
Step-by-step explanation:
<u>Solution by Cross Multiplication</u>
For the equation
35=x36
The cross product is
3×36=5×x
Solving for x
x=3×365
and reducing
x=21.6
<u>Solution by Proportion</u>
Since the equation is an equality
If
36 ÷ 5 = 7.2
Then it is true that
x ÷ 3 = 7.2
Solving for x
x = 3 × 7.2
x = 21.6

The vertices of ∆ABC are A (-2,5), B(-2,4), and C(-5, 3). If ∆ABC is reflected across the line y=-2 to produce the image ∆A’B’C, find the coordinates of the vertex A’ if ∆ABC is reflected across the line x= -2.
