Answer:
-11,8 or 11,8........both are correct
Given:
m is directly proportional to the cube of h.
m = 525 when h= 5.
To find:
The equation connecting m and h.
Solution:
m is directly proportional to the cube of h.
![m\propto h](https://tex.z-dn.net/?f=m%5Cpropto%20h)
...(i)
Where, k is the constant of proportionality.
Putting m = 525 and h= 5, we get
![525=k(5)](https://tex.z-dn.net/?f=525%3Dk%285%29)
![\dfrac{525}{5}=k](https://tex.z-dn.net/?f=%5Cdfrac%7B525%7D%7B5%7D%3Dk)
![105=k](https://tex.z-dn.net/?f=105%3Dk)
Putting k=105 in (i), we get
![m=105h](https://tex.z-dn.net/?f=m%3D105h)
Therefore, the required equation is
.

Answer:
last one
Step-by-step explanation:
x = width
x+6 = length
Area = length times width
x(x + 6) =
+ 6x
+ 6<em>x = 114 (subtract 114 from both sides) </em>
<em />
<em> + 6x -114 = 0</em>
Answer:
The point ( 0,-1) is a solution.
Step-by-step explanation:
y<= (x+1) (x+5)
y>= (x-1)^2 -6
See attached graph.
To prove algebraically, put the point (0,-1) into both equations and see if it is true for both of them.
y<= (x+1) (x+5)
-1 <= (0+1) (0+5)
-1<= 1*5
-1 <=5
True
y>= (x-1)^2 -6
-1 >= (-1)^2 -6
-1 >= 1-6
-1 >=-5
True
The point is a solution
