6. Johnny is a plumber, and Darnel is an electrician. Johnny
charges customers a fee of $150 just to come to their house
and then $75 per hour that he is there. Darnel charges a fee
of $50 for a home visit, plus an additional $125 per hour. How
long do they work to earn the same amount?
a

Answers

Answer 1

Answer:

2 hours

Step-by-step explanation:

Equations for each

Johnny:

J(x) = 75x + 150

Darnel:

D(x) = 125x + 50

In order to get J(x) = D(x) we need to make right sides equal and solve for x:

75x + 150 = 125x + 50  125x - 75x = 150 - 50 50x = 100  x = 2

Choices:
-x
-2x

Answers

The first step was the combine the like terms; in this example he is subtracting the 3x on both sides of the =.

If you were to solve the equation it would look like this:

2x+6=3x-8

-3x -3x

-x+6=-8

-6 -6

-x=-14

/-1 /-1

x=14

Solve the quadratic equation

Answers

Answer:

Our problem is [tex]x^2-2x+6=0[/tex], but as we can see, we are unable to factor. We have to use the quadratic equation to solve.

[tex]x^2-2x+6=0[/tex]

[tex]\frac{-b+-\sqrt{b^2-4ac}}{2a}[/tex]

Positive Quadratic Formula:

[tex]\frac{-(-2)+\sqrt{(-2)^2-4(1)(6)}}{2(1)}[/tex]

[tex]=\frac{2+\sqrt{4-24}}{2}\\=1+\frac{\sqrt{-20}}{2}[/tex]

Negative Quadratic Formula:

[tex]\frac{-(-2)-\sqrt{(-2)^2-4(1)(6)}}{2(1)}[/tex]

[tex]=\frac{2-\sqrt{4-24}}{2}\\=1-\frac{\sqrt{-20}}{2}[/tex]

Since both of our answers are the square root of a negative number, we know that the quadratic equation has no real solution.

*We could have also used the Discriminant Test to determine whether the quadratic equation has real roots or not. However, for our means, the quadratic equation seems enough.

Answer:

D. No real Solution

Step-by-step explanation:

Hello!

Let's use the quadratic formula: [tex]x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}[/tex]

In our equation:

a = 1b = -2c = 6

This comes from the standard form of a quadratic: [tex]ax^2 + bx + c[/tex]

Now, solve:

[tex]x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}[/tex][tex]x = \frac{-(-2) \pm \sqrt{(-2)^2 - 4(1)(6)}}{2(1)}[/tex][tex]x = \frac{2 \pm \sqrt{4 -24}}{2}[/tex][tex]x = \frac{2 \pm\sqrt{-20}}{2}[/tex][tex]x = \frac{2 \pm 2\sqrt{-5}}{2}[/tex][tex]x = 1 \pm \sqrt{-5[/tex]
