uhh dude what's the question?
Step-by-step explanation:
Answer:
16.4 m to the nearest tenth.
Step-by-step explanation:
After the first bounce it rises to a height of 50*0.8 = 40 m.
After the next bounce it rises to 50*(0.8)^2 = 32 m
So after the 5th bounce it rises to 50(0.8)^5 = 16.4 m. (answer).

We can factorise this expression by grouping. First let us arrange it in this way

Let us bracket them like this:

In the first bracket portion, take x as common and in the second expression, take 2 as common.

Answer: (3, -1)
Step-by-step explanation:
Reflecting over y = -x maps
.
So, 
The first two are equivalent to 15 = k + 13
8 = k + 13 - 7 → ( add 7 to both sides )
8 + 7 = k + 13 ⇒ 15 = k + 13 ' is equivalent '
12 = k + 13 - 3 → ( add 3 to both sides )
12 + 3 = k + 13 ' is equivalent '
