Answer:

The graph is shown below.

Step-by-step explanation:

The given inequalities are

6x + y > -3

2x + y \le 4

The related line of both inequalities are

6x + y=-3

2x + y = 4

The table of values are

   Line 1                               Line 2

  x         y                           x         y

  0       -3                           0         4

-0.5      0                            2         0

Plot these ordered pairs on a coordinate plane and connect them by straight lines.

Check both inequalities by (0,0).

6(0) + (0) > -3\Rightarrow 0>-3         True

2(0) + (0) le 4\Rightarrow 0\le 4       True

It means (0,0) is included in the shaded region of both inequalities.

The feasible region is shown below.

The width of a rectangle is (x+1) and the length is (x-6). What is the length and width of the rectangle if the area is 30 squar
jolli1 [7]

Answer:

The length of the rectangle (l) = 3 feet

The width of the rectangle (W) =  10 feet

Step-by-step explanation:

<u><em>Step(i):-</em></u>

<em>Given that the width of the rectangle  = (x+1) feet</em>

<em>Given that the length of the rectangle = ( x-6) feet</em>

<em>The area of the rectangle = 30 square feet</em>

<u><em>Step(ii):-</em></u>

We know that the area of the rectangle

                = length ×width

    30   = ( x+1)(x-6)

    30   = x² - 6x + x -6

⇒ x² - 5 x - 6 = 30

⇒ x² - 5 x - 6 - 30 =0

⇒ x² - 5 x - 36 =0

 x² - 9 x +4x - 36 =0

   x (x-9) +4 ( x-9) =0

   ( x+4 ) ( x-9) =0

     ( x+4 ) =0 and  ( x-9) =0

     x =-4 and x =9

<u><em>Step(iii):-</em></u>

we have to choose x =9

     The length of the rectangle (l) =  x-6 = 9-6 =3

      The width of the rectangle (W) =  x+1 =  9 +1 = 10

<u><em>Final answer:-</em></u>

The length of the rectangle (l) = 3 feet

The width of the rectangle (W) =  10 feet
