6x=3(x - 4) - x plzz
Rom4ik [11]

Answer:

<h2>x = - 3</h2>

Step-by-step explanation:

6x=3(x - 4) - x

<u>Multiply the terms in the bracket</u>

That's

6x = 3x - 12 - x \\ 6x = 2x - 12

Subtract 2x from both sides of the <u>equation</u>

6x - 2x = 2x - 2x - 12 \\ 4x =  - 12

<u>Divide both sides by 4</u>

\frac{4x}{4}  =  -  \frac{12}{4}

We have the final answer as

<h3>x = - 3</h3>

Hope this helps you

What is the solution to the system of equations shown in the graph?
Katen [24]
The solution is where both lines intersect. First find the x-coordinate which we will find by going to the left two units. That means x = -2. Now going up one unit, which gives us y = 1

(-2, 1)

1. Try It # 1 A company sells doughnuts. They incur a fixed cost of $25,000 for rent, insurance, and other expenses. It costs $0
Y_Kistochka [10]

Answer:

The y-intercept is 25000 . The intercept is the fixed cost of the doughnut selling company.

Step-by-step explanation:

In the question, it is given that the fixed cost is $25000 and the expense to produce each doughnut is $0.25.

It is required to find and identify the y intercept.

To do so, use the equation derived in previous part of the exercise to interpret the slope. Compare the equation with standard equation of the line.

Step 1 of 1

The total cost of the company is the sum of fixed cost and the expenses for the doughnut, C=0.25x+25000.

Compare the equation with general linear equation y=mx+c.

The y-intercept is 25000 .

The intercept is the fixed cost of the doughnut selling company.
