Suppose you work as a clerk at a local retail store earning $6 per hour. The amount of your weekly paycheck (before taxes are ta
Viktor [21]

Answer:

x is the independent variable and it represents the number of hours worked per week by the clerk.

Step-by-step explanation:

An independent variable refers to a variable in model that is varied or changed in order to examine its effect on another variable. The other variable is called a dependent variable.

A dependent variable is a variable in a model that changes as a result of a change in the independent variable.

From the question, x is the independent variable and its represent the number of hours worked by the clerk.

F(x) represents the amount of your weekly paycheck and it is the dependent variable that changes as the number of hours worked, x, changes.

For example, since we are given:

F(x) = 6x ............................... (1)

Where;

F(x) = = depemdent variable = Amount of weekly paycheck (before taxes are taken out)

6 = coefficient of x = Earning per hour

x = Independent variable = Number of hours worked

Assuming x = 1, we can substitute this into equation (1) and have:

F(x) = 6 * 1 = $6

But when x = 2, we have:

F(x) = 6 * 2 = $12

Therefore, the dependent variable F(x) changes from $6 weekly to $12 weekly as the independent variable x changes form 1 hour to 2 hours weekly.

Two angles of a triangle measure 12º and 40°.
Sloan [31]

Answer:

12+40= 52

180-52=128

Step-by-step explanation:

Angles in a triangle add up to 180

so if two sides are given , they must be added and subtracted from 180.

which gives us 180-52=128

If f(x) = 2x – 1 and g(x) = ^ – 2, find [g ◦ f](x).
Viefleur [7K]

Answer:

<em>    The value of [g ◦ f](x) = 4x^{2} -4x-1</em>

Step-by-step explanation:

    If f(x) = 2x - 1

    g(x)  = x^{2} -2

    we need to find the value of [g ◦ f](x).

    which means that g(f(x))

    g(f(x)) = (2x-1)^{2} -2

    g(f(x)) = 4x^{2} -4x+1 -2

    g(f(x)) = 4x^{2} -4x-1

<em>     The value of [g ◦ f](x) = 4x^{2} -4x-1</em>
