For the first inequality, subtract 5 from both sides to get

x \geq -2

For the second inequality, subtract 1 from both sides to get

6x < -30

Divide both sides by 6:

x < -5

So, x has to be greater than or equal to -2, or less than -5, which is option D

Aiden is replacing the tile in a rectangular kitchen. The length of the kitchen is nine feet shorter than three times its width,
julia-pushkina [17]

Answer:

Total Cost of tile =  $273.28

Step-by-step explanation:

From the given information:

Let the width be = x

Then, the length of the rectangular kitchen is L = 3x - 9

The perimeter is = 6x

Suppose the cost of the tile = $1.69 a square foot.

Then the total costs to tile the kitchen is calculated as follows:

The Perimeter of the rectangle =  2(L + b)

The Perimeter of the rectangle =  2(3x - 9 + x)

The Perimeter of the rectangle =  2(4x-9)

6x = 8x - 18

- 2x = - 18

x = 18/2

x = 9

Thus, the width = x = 9 ft

the length = 3x - 9 = 3(9) - 9

the length = 27 - 9

the length = 18 ft

Area = L × W

Area = (18 × 9)ft  

Area =   162 sq. ft.

Cost of a Tile = $1.69 per sq. ft.

Thus;

Total Cost of tile = $1.69 × 162

Total Cost of tile =  $273.28

What value must be defined for to remove the discontinuity of this function at ?
olchik [2.2K]

Answer:

Option D. 8

Step-by-step explanation:

we have

f(x)=\frac{x^{2}-16 }{x-4}

Remember that

x^{2}-16 =(x+4)(x-4)

substitute

f(x)=\frac{(x+4)(x-4)}{x-4}

Remove the discontinuity at x=4

Simplify

f(x)=(x+4)

so

Find the value of f(4)

For x=4

f(4)=(4+4)=8
