Answer:

The dependent variable is m

Step-by-step explanation:

A dependent variable is dependent on an independent variable. This variable is dependent on other variable that are measured . The dependent variable are expected to change as a result of the manipulation of the independent variables. Usually as the experiments changes the independent variable the dependent variable are observed and noted.

The independent variable is unaffected by the other variable you are measuring. The independent variable represent a quantity that is been manipulated in an experiment.

According to the question Jenny works as a server at Jefferson restaurant . The more table she is assigned to serve the more money she earns during a shift.

The independent variable is the number of table Jenny served because this is what she has control over.

The dependent variable is the amount of money Jenny earns because the amount of money she earns is dependent on the number of tables she served . Therefore the dependent variable is m

Discussion for Applications of Linear Systems

Lostsunrise [7]

Step-by-step explanation:

There are certain methods for solving a system of equations. Some of which are:

Substitution Method
Elimination Method
Graphing Method

<em>Substitution Method</em>

Substitution method to solve a system of equations is suitable if a variable of a any equation seems isolated or could comfortably be isolated without any ration/fraction resulting.

For example, for the following system of equations

x - 2y = 11....[A]

x = 5 - y....[B]

substituting the value of x = 5 - y from equation [B] into equation [A], so that

(5 - y) - 2y = 11

5 - y - 2y = 11

3y = -6

y = -2

<em>Elimination Method</em>

Elimination method to solve a system of equations is suitable if both equation are in standard form, and just adding or subtracting the equations to determine an equation in one variable.

For example, for the following system of equations

2x + 7y = -5....[C]

5x - 7y = 12....[D]

Adding Equation [C] and Equation [D].

7x + 0 = 7

x = 1

<em>Graphing Method</em>

Sometimes graphing method may be used to solve the system of the equation and visualize the solution.

For example,

y = -2....[E]

y = 3x + 1....[F]

The solution for this system of equation is the point of intersection of both the lines, which is shown in attached figure. The point of intersection is (-1, -2).

Hence, the solution of this system of equations is (-1, -2), as shown in attached figure.

What is the simplified form of 5 square root x^4 • 5 square root x^4

laiz [17]

Answer: C

Step-by-step explanation:

You can write each term into a fraction.

$\sqrt[5]{x^4}$ becomes $x^4^/^5$

When you multiply 2 terms with the same base, you add the exponents.

$x^4^/^5*x^4^/^5=x^4^/^5^+^4^/^5=x^8^/^5$

$x^8^/^5$ is also the same as $x\sqrt[5]{x^3}$

You get this because $\sqrt[5]{x^8} =\sqrt[5]{x*x*x*x*x*x*x*x}$ . When you pull out 5 os x, you are left with x³ on the inside.
