Simplify each sum or difference. State any restrictions on the variables.
maria [59]

Simplification of the equation \frac{x}{3x+9}- \frac{8}{x^{2}  +3x} is equal to (x² -24)/ 3x(x+3), restriction on the variables are x ≠0 , x≠ -3.

As given in the question,

Given equation \frac{x}{3x+9}- \frac{8}{x^{2}  +3x}

Simplify the given equation,

x/ 3(x+3) - 8/x(x+3)

= (x² - 24) / 3x(x+3)

Restriction on the variables for the above equation is,

x≠ 0 , x≠ -3

Therefore, simplification of the equation \frac{x}{3x+9}- \frac{8}{x^{2}  +3x} is equal to (x² -24)/ 3x(x+3), restriction on the variables are x ≠0 , x≠ -3.

Explain why in the Venn Diagram example the number who liked Hip Hop plus the number who liked Country was NOT the same as the n
svlad2 [7]

Answer:

Suppose that you have 50 people that like hip hop and 50 people that like country.

Now, the union of those sets would be 50 + 50 = 100 people, right?

Well, this may be incorrect, because in the 50 people that like hip hop, we may have, for example, 10, that also like country (this means that in the 50 people that like country, we also have 10 that like hip hop).

Then when we are adding 50 + 50 we are counting those 10 people in both groups, and that is why the direct addition may be different than the union of both sets.

In more technical words, the union of two sets is equal to the addition of the elements of both sets minus the elements in the intersection of both sets (in our prior example, the 10 people that like hip hop and country music are the intersection of both sets)

Is the line for the equation y = 1 horizontal or vertical? What is the slope of this line? Select the best answer.
asambeis [7]

Answer:

The answer is the option A

The line is horizontal. The slope is 0

Step-by-step explanation:

we know that

The slope of the line parallel to the x-axis is equal to zero and is called a horizontal line

The slope of the line parallel to the y-axis is undefined and is called a vertical line

In this problem we have

y=1

This is a line parallel to the x-axis

therefore

Is a horizontal line with slope equal to zero
