[tex]\frac{x^2-8x-12}{2x^2+5x-4}[/tex]
1. Find common denominator (LCD)(x + 3)(2x - 1) = [tex]2x^2 + 5x - 4[/tex]2. Multiply bottom to get LCD, then multiply top to matchFirst term: [tex]\frac{x}{x+3} (\frac{2x -1}{2x-1} ) = \frac{2x^2-x}{2x^2+5x-4}[/tex]Second term: [tex]\frac{x+4}{2x-1} (\frac{x+3}{x+3} )=\frac{x^2+7x+12}{2x^2+5x-4}[/tex]Ending expression: [tex]\frac{2x^2-x}{2x^2+5x-4} -\frac{x^2+7x+12}{2x^2+5x-4}[/tex]3. Rewrite terms in a single fraction[tex]\frac{2x^2-x}{2x^2+5x-4} -\frac{x^2+7x+12}{2x^2+5x-4}[/tex] -----> [tex]\frac{(2x^2-x)-(x^2+7x+12)}{2x^2+5x-4}[/tex]4. Subtract, then combine like termsFinal answer: [tex]\frac{x^2-8x-12}{2x^2+5x-4}[/tex]

Slope Formula:[tex]\bold{\displaystyle\frac{y_2-y_1}{x_2-x_1}}[/tex]
Where[tex]\bold{y_2}[/tex] is the y-coordinate of the second point
[tex]\bold{y_1}[/tex] is the y-coordinate of the first point
[tex]\bold{x_2}[/tex] is the x-coordinate of the second point
[tex]\bold{x_1}[/tex] is the x-coordinate of the first point
Check the First example:
[tex]\bf{y_2}[/tex] = 6
[tex]\bf{y_1}[/tex]= -2
[tex]\bf{x_2}[/tex]=3
[tex]\bf{x_1}[/tex] = -9
Plug in the Values[tex]\bf{\displaystyle\frac{6-(-2)}{3-(-9)} }[/tex]
6-(-2) is the same as 6+2; same with 3-(-9)

Is the slope negative? Nope!
How about Option B?

We did it! The slope's actually negative :)
How about Option D (just to make sure the third option is right)
-9-(-8)/-1-2
-9+8/-3
-1/-3
Again we have a negative over a negative.
Therefore, the correct option is[tex]\boxed{\boxed{\bold{Option~C}}}[/tex]

a cast member is selling balloons on main street. he has 4 princess balloon, 5 blue mickey balloons and 1 red mickey balloon. he sells 1 balloon and then another (no replacing). find the probability of selling one blue balloon followed by another blue balloon.
Answers
Answer:
hee-hee!
Step-by-step explanation:
We first have to find how many possible outcomes there are.
We find that out by seeing how many types of balloons are in total.
4 + 5 + 1 = 10
There are 10 possible outcomes.
We then see how many favorable outcomes there are.
There are 5 blue mickey balloons.
That means 5/10 or 1/2.
Then we subtract 1/10 from 5/10.
5/10 - 1/10 = 4/9
We lower the denominator by 1 because the total possible outcomes are also lowered by one.
The probability of the cast member selling another blue balloon after selling the first one is 4/9.
hope this helps :)
