Answer:
x = negative 9/4
Step-by-step explanation:
-2x-11=6x+7
-2x-11+11=6x+7+11
-2x=6x+18
-2x-6x=6x+18-6x
-8x=18
Answer:
5% increase
Step-by-step explanation:
First, find how much it increased:
6300 - 6000
= 300
Then, to find the percent increase, divide 300 by 6000
300/6000
= 0.05
So, there was a 5% increase in the population
Answer:1122

Hve to work out the general equation first by calculating the common difference-16.
Answer:
(- 1/2 , √3/2)
Step-by-step explanation:
t=20π/3
t' = 20π/3 - 6π = 2π/3 (120°) ... 2nd quadrant
If we start from (1,0) of unit circle, the coordinate of terminal point (x,y)
OF/OE = - cos 60° = x / 1 = - 1/2
FE/OE = sin 60° = y/1 = √3/2
