Answer:

Simplifying

7x + -2(x + 1) = 6x + 14

Reorder the terms:

7x + -2(1 + x) = 6x + 14

7x + (1 * -2 + x * -2) = 6x + 14

7x + (-2 + -2x) = 6x + 14

Reorder the terms:

-2 + 7x + -2x = 6x + 14

Combine like terms: 7x + -2x = 5x

-2 + 5x = 6x + 14

Reorder the terms:

-2 + 5x = 14 + 6x

Solving

-2 + 5x = 14 + 6x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-6x' to each side of the equation.

-2 + 5x + -6x = 14 + 6x + -6x

Combine like terms: 5x + -6x = -1x

-2 + -1x = 14 + 6x + -6x

Combine like terms: 6x + -6x = 0

-2 + -1x = 14 + 0

-2 + -1x = 14

Add '2' to each side of the equation.

-2 + 2 + -1x = 14 + 2

Combine like terms: -2 + 2 = 0

0 + -1x = 14 + 2

-1x = 14 + 2

Combine like terms: 14 + 2 = 16

-1x = 16

Divide each side by '-1'.

x = -16

Simplifying

x = -16

Write the linear equation in slope intercept form
soldi70 [24.7K]
Y=5x


Explanation:


You would take two points and use the slope formula

Y2-y1/x2-x1

So I took the points (0,0) and (1,5)

5-0/1-0
5/1
5= the slope

So now we know y=5x+b and since it shows us on the graph where the line crosses the y axis we know the y intercept will be zero because it crosses at 0. When the y-intercept is 0 we don’t even need to list it.

1) A light bulb producing company states that its lights will last an average of 1200 hours with a standard deviation of 200 hou
Ronch [10]

The mean ( average ) is given as 1200 hours.

The standard deviation is 200, sample size is 100.

Find the standard error:

√(200^2 / 100) = 20

Now calculate the confidence interval. For 95% the Z number is 1.96

Multiply Z by the standard error:

1.96 x 20 =39.2

Now find the range that the mean should be within:

1200 - 39.2 = 1160.8

1200 + 39.2 = 1239.2

The samples should be between 1160.8 and 1239.2 for a 95% confidence interval.

Since the average was 1050, which is below 1160.8 the bulbs are not in compliance.
