Group like terms together. We'll get 4x on the left side of our equation and 16 on the right side. Then 4x = 16, and x = 4 (answer)
The formula of a slope:

We have the points (-8, -20) and (5, 2). Substitute:

Answer: The slope is 
We know that sin2x=2sinxcosx
(search the net for proof if you wish)
So the original equation becomes
2sinxcosx-sinx=0
The two terms both have sinx that can be taken out to get:
sinx(2cosx-1)=0
This is true if sinx=0 or 2cosx-1=0 , rewritten: cosx=1/2
sinx=0 than x=2kπ
cosx=1/2 than x=π/3+2kπ
where k is an integer
Answer:
for m∠SRQ x = 3
for m∠QRP x = 5
Step-by-step explanation:
1. 6x +2. 6 is being multiplied by a number so to find that number we do teh opposite
6x/2 = 3
drop the x then u have x = 3
2. 2x+10. 2 is being muliplied by a number so to find that number we do teh opposite
10/2x = 5
drop the x then u have x = 5
This is how it is done. Let me know if you have questions...
