Answer: C
Step-by-step explanation: With inverse equations, you switch y and x (y=f(x)) and undo/reverse the steps towards x.
1. Multiply by 3
2. Add 2
Equation by itself
0. x
1. 3(x)
2. 3(x+2)

Correct answer is B. (second Choice)
Step-by-step explanation:
Hello from MrBillDoesMath!
Answer:
-2c^3 - 4c^2 + 1
Discussion:
(-7c^3 + 5c^2 + 1) + (5c^3 - 9c^2) = => combine like terms
(-7c^3 + 5c^3) + (5c^2 - 9c^2) + 1 =
-2c^3 - 4c^2 + 1
Thank you,

Answer:
Step-by-step explanation:
We are to show that
<u>Proof:</u>
From trigonometry identity;
From trigonometry, 2sinAcosA = Sin2A
Also note that sin(B-C) = sinBcosC - cosBsinC
sin420cos140 - cos420sin140 = sin(420-140)
The resulting equation becomes;
=
