Answer:
x>8
Step-by-step explanation:
you first subtract 13 from both sides resulting in -2x<-16. Then you divide -2 on both sides and when you divide a negative on both sides you have to change the sign, -16/-2=8 so x>8.
Answer:
D
Step-by-step explanation:
A is wrong because on the point -4, the function is equal to -12 and a states the local minimum on [-4, -2] is equal to zero. Since -12 < 0, A is wrong.
B is wrong because the function never even reaches 25 on the interval [-2, -2]
C is wrong because we can see that 3.9 is zero and the function is decreasing there. fro this we can determine the functions value at x = 4 is less than 0, meaning the minimum value is also less than 0.
Lastly, we can see that the lowest point fro 4 to 7 is at -7, meaning that D is correct.
Hope that helps. :)

Answer:
<u>y = 3/2x + 6</u>
Step-by-step explanation:
<u>Equation of the given line</u>
- slope = rise/run = -2/3
- y-intercept = (0, -2)
- Equation is y = -2/3x - 2
<u>Perpendicular</u>
- Slope is the negative reciprocal
- m ⇒ -(1/[-2/3]) = 3/2
- Intersection point is (-2, 3)
<u>Using Point-slope equation</u>
- y - 3 = 3/2 (x + 2)
- y - 3 = 3/2x + 3
- <u>y = 3/2x + 6</u>
First we simplify like terms:
4x-2x+1/2-5/7=1/2-x
2x-3/14=1/2-x
Then you add x to both sides to get everything with the variables together.
3x-3/14=1/2
Finally, you add 3/14 to both sides for the same reason.
3x=10/14 (simplifies to 5/7)
Then we divide by 3 to get x alone.
x=5/21
