A sales manager for an advertising agency believes that there is a relationship between the number of contacts that a salesperso
serg [7]

Using variable concepts, of dependent and independent variables, it is found that the dependent variable is the amount of sales dollars earned.

<h3>What is the relation between a function and the dependent and independent variables?</h3>

  • A function has the following format: y = f(x).
  • In which each value of y is a function of one value of x, and thus, <u>x is the independent variable and y is the dependent variable</u>.
  • That is, the input of the function is the independent variable and the output is the dependent variable.

In this problem, the manager believes that the amount of sales dollars earned is a function of the number of contacts that the salesperson makes, hence:

  • The number of contacts is the independent variable.
  • The amount of sales dollars earned is the dependent variable.

Write an equation of the line passing through each of the following pairs of points.
slavikrds [6]

Answer:

y=\frac{1}{3}+\frac{13}{3}

Step-by-step explanation:

We want to write the equation of a line that passes through (5, 6) and (-1, 4).

First, let's find our slope. We can use the slope formula:

m=\frac{y_2-y_1}{x_2-x_1}

Let's let (5, 6) be (x₁, y₁) and let's let (-1, 4) be (x₂, y₂). So, our slope is:

m=\frac{4-6}{-1-5}

Subtract:

m=-2/-6

Reduce:

m=1/3

So, our slope is 1/3.

Now, we can use the point-slope form, which is:

y-y_1=m(x-x_1)

For consistency, let's let (5, 6) be (x₁, y₁). We will also substitute 1/3 for m. So:

y-6=\frac{1}{3}(x-5)

Distribute:

y-6=\frac{1}{3}x-\frac{5}{3}

Add 6 to both sides:

y=\frac{1}{3}x-\frac{5}{3}+\frac{18}{3}

Add:

y=\frac{1}{3}+\frac{13}{3}

And we're done!

What must the value of x be, so that a parallel to b, m∠2 = 70°, and m∠7=(3x + 10)°?
Ksju [112]
70=3x+10
Subtract 10 from both sides
60=3x
Divide both sides by 3
20=x
x=20
