Answer:

See below. The answer is incomplete, I couldn't post it.

Step-by-step explanation:

Considering a function $f$ , it is said to be discontinuous when it has a hole or breaks, it means places where $f(x)$ cannot be evaluated. For example, when the denominator equals to 0, it is not defined.

Finding the slope using two points:

The formula for slope is

$\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

In this case...

(-4, 3) and (5, 3)

$y_{2} =3\\y_{1} =3\\x_{2} =5\\x_{1} =-4$

^^^Plug these numbers into the formula for slope...

$\frac{3-3}{5 - (-4)}$

$\frac{0}{9}$

B. 0

^^^This is your slope

Hope this helped!

Jessica made plans to weave a rectangular jute rug, but she needs to update the plans to change the dimensions of the rug. The o

loris [4]

Answer:

Length of rug in original design is 36 inches .

Width of rug in original design is 60 inches .

The problem says that the new design has length 3x inches longer and x inches wider than the rug in the original plans .

New length of rug would be 3x inches longer than the original design which is 36 inches .

Thus new length of rug is ( 3x + 36 ) inches .

New width of rug is x inches wider than the rug in the original plans which is 60 inches in original plan .

Thus new width of rug is ( x + 60 ) inches .

Area of rectangle is Length * Width

Area of new rug is ( 3x + 36 ) * ( x + 60 )

We distribute the terms using FOIL method .

( 3x + 36 ) *( x + 60 ) = 3x ( x + 60 ) + 36 ( x + 60 )

= 3x² + 3x * 60 + 36 x + 36 * 60

= 3x² + 180 x + 36 x + 2160

Combining like terms , 3x² + 216 x + 2160

Thus the area of the rug with the new dimensions is

( 3x + 36) ( x + 60 ) = 3x² + 216 x + 2160 .
