The choose a. 3x+12

( \frac{f}{g} )(x) =  \frac{3 {x}^{2} - 48 }{x - 4}  =  \frac{3( {x}^{2} - 16) }{x - 4}  \\  \\  =  \frac{3(x - 4)(x  +  4)}{x -4}  \\  \\  = 3(x + 4) \\  = 3x + 12

I hope I helped you^_^

Which of the following indicates the subtraction property of equality when solving the equation 4(x + 9) + 5 = 3x − 8? Question
jeka94

Answer: 4(x + 9) = 3x − 8 − 5

Step-by-step explanation:

Hi, to answer this question we have to analyze the equation given:

4(x + 9) + 5 = 3x − 8

The subtraction property of equality states that if we subtract the same number from both sides of the equation, the equality remains.

So, if we subtract 5 from both sides:

4(x + 9) + 5-5 = 3x − 8 -5

4(x + 9) = 3x − 8 − 5  

Feel free to ask for more if needed or if you did not understand something.

PROBLEMS TO SOLVE

A graph for the data (time and distance) shown in the given table is plotted in the image attached below.

<h3>What is a graph?</h3>

A graph can be defined as a type of chart that's commonly used to graphically represent data on both the horizontal and vertical lines of a cartesian coordinate, which are the x-axis and y-axis.

<h3>What is a linear function?</h3>

A linear function can be defined as a type of function whose equation is graphically represented by a straight line on the cartesian coordinate.

This ultimately implies that, the data of a linear graph are directly proportional and as such as the value on the x-axis increases or decreases, the values on the y-axis also increases or decreases.

In this exercise, you're required to plot a graph for the data (time and distance) that are recorded for an object that is starting from rest.

By critically observing the graph (see attachment) which models the data in the given table, we can infer and logically deduce that the linear function is given by:

y = 67.814x

You're uncle is having a new roof installed in his house. The roof is a square pyramid. The side length of the base of the roof
Kaylis [27]

Answer:

The height of the roof in his house is 72.43 ft.

Step-by-step explanation:

The volume of square pyramid is :

V=\frac13 Bh

B= area of the base.

h= the height.

Given that,

The roof is a square pyramid in shape. The volume of the roof is 18929.333 cubic feet.

The side length of the base of the roof is 28 feet.

Since the base of the roof is square in shape.

The area of the square is = side²

The area of the base is =(28×28) square feet

                                       =784  square feet

Assume the height of the roof be h ft.

Then, the volume of the roof is = \frac13 Bh

                                                   =\frac13 \times 784 \times h square feet.

According to the problem,

\frac13 \times 784 \times h= 18929.3333

\Rightarrow h=\frac{18929.3333\times 3}{28}

\Rightarrow h\approx 72.43 ft.

The height of the roof in his roof is 72.43 ft.
