Answer:

(f-g)(x)

f(x)-g(x)

x^{2} -6x-27-x+9

x^{2} -7x-18

----------------------

(f*g)(x)

=f(x)g(x)

(x^{2} -6x-27)(x-9)

=x^{3} -15x^{2}+27x+243

----------------------

\frac{f}{g} (x)

\frac{x^{2} -6x-27}{x-9}

\frac{(x-9)(x+3)}{x-9}

x+3

-----------------------

(f+g)(x)

f(x)+g(x)

=x^{2} -6x-27+x-9

=x^{2} -5x-36

The graph of a system of equations with the same slope and the same y-intercepts will have no solutions.
Rasek [7]
If 2 equations have the same y-intercept, they are overlapping, which means they have infinite solutions. So there is no way that 2 equations with the same y-intercept will have no solution. Thus your answer is: C)Never.

What is different between solving inequalities and absolute value inequalities?
Ivenika [448]

Answer:

The absolute number of a number a is written as

|a|

And represents the distance between a and 0 on a number line.

An absolute value equation is an equation that contains an absolute value expression. The equation

|x|=a

Has two solutions x = a and x = -a because both numbers are at the distance a from 0.

To solve an absolute value equation as

|x+7|=14

You begin by making it into two separate equations and then solving them separately.

x+7=14

x+7−7=14−7

x=7

or

x+7=−14

x+7−7=−14−7

x=−21

An absolute value equation has no solution if the absolute value expression equals a negative number since an absolute value can never be negative.

The inequality

|x|<2

Represents the distance between x and 0 that is less than 2

Whereas the inequality

|x|>2

Represents the distance between x and 0 that is greater than 2

You can write an absolute value inequality as a compound inequality.

−2<x<2

This holds true for all absolute value inequalities.

|ax+b|<c,wherec>0

=−c<ax+b<c

|ax+b|>c,wherec>0

=ax+b<−corax+b>c

You can replace > above with ≥ and < with ≤.

When solving an absolute value inequality it's necessary to first isolate the absolute value expression on one side of the inequality before solving the inequality.

Step-by-step explanation:

Hope this helps :)
