To reflect a function across the x axis, we want to turn all the x values that were once positive negative and vice versa. That means we want f(-x), which is:
Answer:
5) we get a=6
6) we get c=8
Step-by-step explanation:
The triangles given are similar.
When the triangles are similar, the ratio of corresponding sides are also similar.
5) If c = 12, find a
We will use the ratio
Now cross multiply to find value of a
So, we get a=6
6. If b = 6.4, find c
We will use the ratio
Now cross multiply to find value of b
So, we get c=8
