Answer: x=-7 and x=9
Asummung you are solving for x
x+7=0
x=-7
-x+9=0
-x=-9
x=9
A. It's a composite function, so basically, wherever you see a p, replace it with 5t, because we are given that information. So, your answer is:
B. Let's use the function we created, and just plug in 2 for t:
![A[p(2)] = 10(2) \pi](https://tex.z-dn.net/?f=A%5Bp%282%29%5D%20%20%3D%2010%282%29%20%5Cpi%20)
![A[p(2)] = 62.83](https://tex.z-dn.net/?f=A%5Bp%282%29%5D%20%3D%2062.83)
So, your answer is
(approximately)
62.83 units².
Answer:
x = 7
Step-by-step explanation:
Since BD is the angle bisector of ∠ABC, then
∠ABD = ∠CBD, that is
2x + y = 14 + y ( subtract y from both sides )
2x = 14 ( divide both sides by 2 )
x = 7
He's percent of decreased, will be .72% or 72% decrease.
