Answer:
x=3
Step-by-step explanation:
minus 3x on both sides
after you've subtracted 3x from both sides you then need to minus 12 from both sides
Last step is going to be dividing by 2 and you should get the answer of 3

Answer:
m=2 and b=-8
Step-by-step explanation:
This equation is organized in slope-intercept form, y=mx+b. In this form, m is the slope and b is the y-intercept.
When given the equation, y=2x-8, we can see that 2 is in the place of m and -8 is in the place of b. The reason the y-intercept isn't 8 is that y=2x-8 can be written as y=2x+(-8) since y=mx+b involves addition. Therefore, the slope is 2 and the y-intercept is -8.
m=2 and b=-8
I hope this helps!
Answer:
A, C
Step-by-step explanation:
Actually, those questions require us to develop those equations to derive into trigonometrical equations so that we can unveil them or not. Doing it only two alternatives, the other ones will not result in Trigonometrical Identities.
Examining
A) True

Double angle 
B) False,
No further development towards a Trig Identity
C) True
Double Angle Sine Formula 

D) False No further development towards a Trig Identity
