Answer:
the answer is bc you go over negative two and up five (-2,5)
The function is increasing when the slope is greater than zero and decreasing when the slope is less than zero. Slope is (y2-y1)/(x2-x1) or the change in y divided by the change in x.
In this case the function is decreasing when x=[-8,-5) and when x=[4,8)
So in interval notation: x=[-8,-5)U[4,8)
She is correct, first of all, to add 7/8 and 5/6; you must have common denominators so make 7/8 into 42/48 and make 5/6 into 40/48. Then just add them together now, and it will be 82/48. This when you divide 82/48 it will be 1 17/24. So, your answer is, yes, Kit is right.
9 x ≥ 117
Divide both sides by 9 :
9 x / 9 ≥ 117 / 9
x = 117 / 9
x ≥ 13
hope this helps!
If the perimeter is 39 what you have to do is 39 - 8.5 - 8.5 that will give you 22 and divide 22/2 and that gives you 11. So 11 is the length
