Answer:

All but the second one

Step-by-step explanation:

Find the inverse of each function:

b(x)=x^2+3

y=x^2+3

x=y^2+3

x-3=y^2

sqrt(x-3)=y

This inverse function is a function

d(x)=-9

y=-9

This doesn't have an inverse function

m(x)=-7x

y=-7x

x=-7y

-1/7x=y

This inverse function is a function

p(x)=|x|

y=|x|

x=|y|

x=y

This inverse function is a function

Therefore, all but the second function have inverses that are functions

Answer:

All but the second one have inverse functions

Step-by-step explanation:

Natalee transferred water from a square pyramid to a cube. To calculate how many times she will need to dump the water from the pyramid into the cube to completely fill the cube, we divide the volume of the cube by the volume of the square pyramid. Hence:

Number of times = volume of cube / volume of pyramid

The perimeter of the pyramid base = 25 in, hence the length of one side of the bae = 25 / 4 = 6.25 in

Volume of square pyramid  = base² × (height / 3) = (6.25 in)² * (5 in / 3) = 65.1 in³

Volume of cube = 125 in³

Number of times = 125 in³ / 65.1 in³ = 1.92

The amount of times that she will need to dump the water from the pyramid into the cube to completely fill the cube is 1.92.

The capacity of a container of any shape is called the volume.

Natalee transferred water from a square pyramid to a cube. Then,

Given is the perimeter of the pyramid base = 25 in

So, the length of one side of the base b= 25 / 4 = 6.25 in

Volume of square pyramid  = b² × (h/ 3) = (6.25 in)² * (5 in / 3) = 65.1 in³

Volume of cube = 125 in³

Number of times = volume of cube / volume of pyramid

Number of times = 125 in³ / 65.1 in³ = 1.92

Answer:

B. Robert's sister's sales total $18.00.

E. Robert's sister's sales are represented by x when solving 3.5x = 63 .

Step-by-step explanation:

Let

Robert sister's sales = x

Robert sales = 2.5 * x

= 2.5x

Total sales = Robert sister's sales + Robert sales

63 = x + 2.5x

63 = 3.5x

Divide both sides by 3.5

x = 63 ÷ 3.5

= 18

x = $18.00

Robert sales = 2.5x

= 2.5(18)

= $45.00

A. Robert's sales are represented by x when solving 3.5x=63 .

No

B. Robert's sister's sales total $18.00.

The function that best models the data set is y = 3x + 11

"The slope of the line passing through points [tex](x_1,y_1),(x_2,y_2)[/tex] is,

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]"

"The equation of the line passing through points [tex](x_1,y_1),(x_2,y_2)[/tex] is, [tex]\frac{y-y_1}{y_2-y_1} =\frac{x-x_1}{x_2-x_1}[/tex] "

For given question,

If we draw the line of best fit, then the the line would pass through points (3, 20) and (8, 35)

Let [tex](x_1,y_1)=(3, 20),(x_2,y_2)=(8, 35)[/tex]

Then the equation of the line would be,

[tex]\Rightarrow \frac{y-y_1}{y_2-y_1} =\frac{x-x_1}{x_2-x_1} \\\\ \Rightarrow \frac{y-20}{35-20} =\frac{x-3}{8-3} \\\\ \Rightarrow \frac{y-20}{15} =\frac{x-3}{5} \\\\ \Rightarrow y-20=15\times \frac{x-3}{5}\\\\ \Rightarrow y-20=3(x-3)\\\\ \Rightarrow y-20=3x-9\\\\ \Rightarrow y=3x+11[/tex]

Therefore, the function that best models the data set is y = 3x + 11
