I took the test and the answer was
-5
If -2 (s - 7) > 4s + 8
then -2s + 14 > 4s + 8
14 - 8 > 4s + 2s
6 > 6s
∴ <span>all real numbers s such that -2(s - 7) > 4s + 8 are s < 1</span>
So you need to find the slope and the y- intercept. So, the slope is always the coefficient on the x. In this case it is 4. The y-intercept is the other number. In this case it is -5. So the slope is 4 and the y-intercept is -5. On your graph (the y axis) find -5. Then you go up 4 and to the right 1 because of four were a fraction it would be 4/1. Keep going up four and right one a couple times. Then reverse it. Go down 4 left 1. That as a fraction would look like -4/-1. Then connect your points and make it a line!
Answer:
18
Step-by-step explanation:
=2(cot²A+1)
=2cosec²A. [` . ` cot²A+1=cosec²A] =2(1/sinA)²
[' . 'cosecA=1/sinA]
=2×3²/1
=2cot²a+2=2×8+2=16+2=18
