Answer:

I think your forgot to add some parts of this question, because you can't do anything with this except simplify it down a little maybe. But, I will provide the simplified version of this.

\frac{x-4}{x^2-2x}+\frac{4}{x^2-4}

= \frac{x-4}{x\left(x-2\right)}+\frac{4}{x^2-4}

= \frac{x-4}{x\left(x-2\right)}+\frac{4}{\left(x+2\right)\left(x-2\right)}

= \frac{\left(x-4\right)\left(x+2\right)}{x\left(x-2\right)\left(x+2\right)}+\frac{4x}{\left(x+2\right)\left(x-2\right)x}

= \frac{\left(x-4\right)\left(x+2\right)+4x}{x\left(x-2\right)\left(x+2\right)}

= \frac{x+4}{x\left(x+2\right)}

Step-by-step explanation:

Hope this helped!

Given: 2x + b &gt; -3. Find the value of b so that x &gt; 3<br>Help a s a p please
masya89 [10]

Answer:

Step-by-step explanation:

To find the value of b, we need to isolate it on one side of the inequality. We can do this by subtracting 2x from both sides, which gives us b > -3 - 2x.

Since we want x to be greater than 3, we can plug in the value 3 for x on the right-hand side of the inequality. This gives us b > -3 - 6, or b > -9.

Therefore, the value of b that makes the inequality true is any value that is greater than -9. For example, b could be -8, -7, -6, or any other value that is greater than -9.

To check if our solution is correct, we can plug in the value of b and the value of x (3) into the original inequality to see if it is true. If we plug in -8 for b and 3 for x, we get the inequality 2x + b > -3, which simplifies to 2 * 3 + (-8) > -3, or 6 - 8 > -3, which is true. Therefore, our solution is correct.

You have decided to purchase a car for $22,346.16. The credit union requires a 10% down payment and will finance the
sukhopar [10]

Answer:

(b) \$24,169.60

Step-by-step explanation:

Given:  Cost of car is \$22,346.16

            Sales tax is 7.6\%    

             The license and title  charges are \$125.13

To find: The amount that the credit union will finance.

Solution:

We have,  

Cost of car=\$22,346.16  

Sales tax is 7.6\% of \$22,346.16

Therefore,  

sales tax =\frac{7.6}{100}\times22,346.16=\$1698.31

The license and title  charges =\$125.13

Now, the amount that the credit union will finance is

cost of car+sales tax+the license and title  charges

=\$22346.16+\$1698.31+\$125.13

=\$24,169.60

Hence, the amount that the credit union will finance is \$24,169.60.

So, (b) \$24,169.60 is correct.

b) Put everything in order and find the middle
10, 10, 10, 20, 30, 30, 30, 30, 40, 50, 50, 50, 60, 60, 70, 70, 2040
                                             ^^
So 40 is in the middle, making it the median

c) Add all of the values together and divide by the total number of values.
10 + 10 + 10 + 20 + 30 + 30 + 30 + 30 + 40 + 50 + 50 + 50 + 60 + 60 + 70 + 70 + 2040 = 2660
2660 / 17 = 156.5
