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)

[tex]\bf{\displaystyle\frac{6+2}{3+9}}[/tex]

Simplify:

[tex]\bf{\displaystyle\frac{8}{12}}[/tex]

Is the slope negative? Nope!

How about Option B?

[tex]\bf{\displaystyle\frac{7-9}{5-6}}[/tex]

[tex]\bf{\displaystyle\frac{-2}{-1}}[/tex]

Right now it seems like the slope's negative, huh? Well, wait for it...

[tex]\bf{2}[/tex]

Kaboom!

Please remember that

[tex]\bigstar^\circ[/tex] A negative number multiplied/divided by a negative number equals... a positive! :-)

We have 2 options left: C & D.

[tex]\displaystyle\frac{-8-1}{8-(-8)}[/tex]

[tex]\displaystyle\frac{-8-1}{8+8}}[/tex]

[tex]\displaystyle\frac{-9}{16}}[/tex]

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]

The 20 pound bag is a better by for only $66.98

Step-by-step explanation:

The large bag is better because the small bag is $27.93 for 7 pounds 7x3=21,so 3x27.93=83.79 is $16.81 more than the cost for the large bag

Can someone help me with this math equation? Can you explain how to work it out also?

Answers

Answer: 50

Explanation:What we know:The numerator is 6The denominator is equal to (3*5)^(-2)In fraction-style equations, the numerators are divided by denominatorsNegative exponents are equal to (base)^|power|, and then reversing the products place in the fraction

How to solve:

    By utilizing our knowledge of the PEMDAS solving method, negative powers, and fraction-style equations, this problem can be solved with a simple step-by-step procedure

Process:Exponent

Set up equation                                                            6 / [3 * 5^(-2)]

Rewrite power                                                              6 / [3 * (5 * 5)]

Simplify power                                                              6 / [3 * (25)]

Invert power                                                                  6(25) / 3

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.

Answers

Answer:

8/8

Step-by-step explanation:

There are two pies, and each one was cut into fourths. There are four fourths in a whole, and since there are two wholes, there are two four fourths (I don't know if this makes sense).

Basically, multiply how many fourths (four per pie) by how many pies there are.

4 x 2 = 8

There are 8 pieces.

8/8 because with there being 2 pies with 4 slices each then 4+4=8 so it’s 8/8
