juin [17]

Answer:

Step-by-step explanation: Explanation:

If

L

,

H

and

W

represent the length, height and width of the prism, then the volume of the rectangular prism is :

V

=

L

.

H

.

W

............. (1)

Given :

V

=

x

+

11

x

x

−

;

............... (2)

W

=

(

x

−

1

)

;

   

H

=

(

x

+

8

)

.

Let

L

=

(

x

+

l

0

)

be the expression for the length, then the RHS of equation (1) becomes

L

.

H

.

W

=

(

x

−

l

0

)

(

x

+

8

)

(

x

−

1

)

,

   

   

   

   

=

(

x

+

l

0

)

(

x

+

7

x

−

8

)

   

   

   

   

=

(

x

+

l

0

)

(

x

7

x

)

x

2

+

(

7

l

0

−

8

)

x

−

8

l

..... (3)

Comparing this to the LHS of equation (1), we get the following set of equations to solve for

l

l

l

=

32

;

l

=

4

Therefore

L

=

(

x

+

Y is inversely proportional to x. If y= 400 when x =2 find y when x= 200
o-na [289]

Answer:  4

<u>Step-by-step explanation:</u>

Inversely proportional means xy = k, where k is the constant of proportionality

First, find k when x = 2 and y = 400 ----> 2(400) = k   --> 800 = k

Then, find y when x = 200 (knowing that k = 800)

                                    200y = 800

                                           y = 4
