Answer:
x∈{ -11,-10,-9,-8,-7,-6,-5,-4,-3,-2,-1,0, 1,2,3,4}
Step-by-step explanation
2x+9<0
-9 -9
2x<-9
:2 :2
x<9/2
x<4.5
x>-12
x could be one of these numbers { -11,-10,-9,-8,-7,-6,-5,-4,-3,-2,-1,0, 1,2,3,4}
-11 , -10 , -9 , -8 , -7 , -6 , -5
Step-by-step explanation:
here is an solution :
46
What is given....
The length which is 12.
The area which is 132
We can use both of those to find the missing height
A = l * h
132 = 12 * h
132/12 = 12/12 * h
11 = h
Now that we found what "h" is, we can use that to find the perimeter....
Perimeter is when you add up all of the sides of a shape
L = 12
H = 11
There are 4 sides in a rectangle ( 2 sides for the height, and 2 sides for the lengths)
12 + 12 + 11 + 11
24 + 22
The perimeter of the rectangle is 46
Hope this helped!

slope=change in y/change in x
one way is t pick 2 points, (x1,y1) and (x2,y2)
the slope is (y2-y1)/(x2-x1)
pick some points
(8,4) and (8,0)
slope=(0-4)/(8-8)=-4/0=undefined
the slope is undefined
there is no slope.
