An electrician charges a base fee of $70 plus $45 for each hour of work. The minimum the electrician charges is $160. Create a table that shows the amount the electrician charges for 1, 2, 3, and 4 hours of work. Determine the domain and range of the relation in context and explain whether or not this represents a function.

Answers

Answer:

1) See below for table.

2) Domain: [tex]\{1, 2, 3, 4\}[/tex]

Range: [tex]\{160, 160, 205, 250\}[/tex]

Yes, this is a function.

Step-by-step explanation:

We know that the electrician charges a base fee of $70 plus $45 for each hour of work.

We also know that the minimum the electrician charges is $160.

Let's write an equation. Let x denote the number of hours worked and y denote the total price. There's also a base fee of $70. So, we can write the following equation:

[tex]y=45x+75[/tex]

Part 1)

Let's create our table for 1, 2, 3, and 4 hours. To do so, we simply need to substitute each value for x in our equation.

1 Hour:

We have:

[tex]y_1=45(1)+70[/tex]

Multiply and add:

[tex]y_1=45+70=\$115[/tex]

However, notice that the minimum the electrician charges is $160. Therefore, for one hour of work, the electrician will still charge $160. So:

[tex]y_1=\$160[/tex]

2 Hours:

Substitute 2 for x:

[tex]y_2=45(2)+70=90+70=\$160\\[/tex]

So:

[tex]y_2=\$160[/tex]

3 Hours:

Substitute 3 for x:

[tex]y_3=45(3)+70=135+70=\$205[/tex]

So:

[tex]y_3=\$205[/tex]

4 Hours:

Substitute 4 for x:

[tex]y_4=45(4)+70=180+70=\$250[/tex]

So:

[tex]y_4=\$ 250[/tex]

Therefore, for 1, 2, 3, and 4 hours of work, the prices will be $160, $160, $205, and $250, respectively.

We can create the following table (please scroll down to see the table. Also, y is measured in dollars).

Part 2)

The domain of a relation are the input values.

In this context, our input values are the amount of hours worked, and we calculated for 1, 2, 3, and 4 hours of work.

Therefore, our domain in this context is:

[tex]\{1, 2, 3, 4\}[/tex]

The range of a relation are the output values.

In this context, the output values are the price for x hours of work.

Therefore, our range in this context is:

[tex]\{160, 160, 205, 250\}[/tex]

This relation does represent a function. Remember that a function cannot have repeating input values. In other words, no one input can be equal to two or more different outputs. However, one output can be mapped to two or more different inputs.

For our table, none of the inputs are repeating. So, our relation is a function.

And we're done!

x - y = 4 and x + y = 9

Answers

Answer:

5-1=4 and 5+4=9

Step-by-step explanation:

[tex]\huge\red{ƛƝƧƜЄƦ}[/tex]

System of Linear Equations entered :

[1] x - y = 4

[2] x + y = 9

Graphic Representation of the Equations :

y + x = 4 y + x = 9

Solve by Substitution :

// Solve equation [2] for the variable y

[2] y = -x + 9

// Plug this in for variable y in equation [1]

[1] x - (-x +9) = 4

[1] 2x = 13

// Solve equation [1] for the variable x

[1] 2x = 13

[1] x = 13/2

// By now we know this much :

x = 13/2 y = -x+9

// Use the x value to solve for y

y = -(13/2)+9 = 5/2

Solution :

{x,y} = {13/2,5/2}

Hank has the choice of taking out a 30-year loan for $165,000 at 9.1% interest, compounded monthly, or the same loan at 20 years for a higher monthly payment. How much more is the monthly payment for the 20-year loan than the monthly payment for the 30-year loan? O A. $56.47 O B. $155.66 O c. $99.19 OD. $90.05​

Answers

If Hank has the choice of taking out a 30-year loan for $165,000 at 9.1% interest. The amount that the monthly payment for the 20-year loan is more than the monthly payment for the 30-year loan is: B. $155.66.

How to find the monthly payment?

For 30-year loan

P= principal = $165,000

r = Rate = 9.1% /12 = 0.00758

n = Number of months= 30years × 12 months = 360

So,

Monthly payment = 165,000×0.00758 × ( 1+0.00758)^360 / (1+0.00758)^360 -1

Monthly payment = 165,000×0.00758 × ( 1.00758)^360 / (1.00758)^360 -1

Monthly payment = 18,957.7574/14.15771760

Monthly payment = $1,339.04

For 20-year loan

P= principal = $165,000

r = Rate = 9.1% /12 = 0.00758

n = Number of months= 20years × 12 months = 240

So,

Monthly payment = 165,000×0.00758 × ( 1+0.00758)^240 / (1+0.00758)^240 -1

Monthly payment = 165,000×0.00758 × ( 1.00758)^240 / (1.00758)^240 -1

Monthly payment = 7,660.239666/5.12476186615

Monthly payment = $1,494.7

Difference = $1,339.04 - $1,494.7

Difference = $155.66

Therefore the correct option is B.

4 cachorros se terminan un paquete de croquetas en 6 días, si tuviéramos 3 cachorros ¿cuantos días duraría el paquete ?

Answers

Answer:

4 1/2 días.

Step-by-step explanation:

En la pregunta se nos dice que:

4 cachorros terminarán un paquete de croquetas en 6 días, si tuviéramos 3 cachorros, ¿cuántos días duraría el paquete?

4 cachorros = 6 días

3 cachorros = y días

Cruz multiplicar

4 cachorros × y = 3 cachorros × 6 días

y = 3 cachorros × 6 días / 4 cachorros

y = 18/4

y = 4 2/4

y = 4 1/2 días

Por lo tanto, el paquete de croquetas para 3 cachorros tendrá una duración de 4 1/2 días.

w = 3

Hope this helps

plz mark as brainliest!!!!!!

Answer:

[tex]w=3[/tex]

Step-by-step explanation:

[tex]9 = -7w + 12w -6[/tex]

Start by combining like terms ([tex]-7w+12w[/tex]):

[tex]9=5w-6[/tex]

Add [tex]6[/tex] to both sides of the equation:

[tex]15=5w[/tex]

Divide both sides of the equation by the coefficient of [tex]w[/tex], which is [tex]5[/tex]:

[tex]3=w[/tex]

_

Check your work by substituting the solved value of [tex]w[/tex] ([tex]3[/tex]), into the initial equation:

[tex]9 = -7(3) + 12(3) -6[/tex]

Multiply:

[tex]9=-21+36-6[/tex]

Combine like terms:

[tex]9=9[/tex]

Since both sides of the equation are equal, our answer is correct!
