Answer:

Step-by-step explanation:

Let's see how well I can explain this. $\frac{\pi}{6}$ is the same as a 30 degree angle which is in quadrant 1. If you picture the unit circle, right in the center of it is the origin. If you draw a straight line from 30 degrees and through the center (the origin), you will automatically "connect" with the reference angle of 30 (this is true for ALL angles on the unit circle). This puts us in quadrant 3. In quadrant 3, x is negative and so is y. So the terminal point of the reference angle for 30 degrees has the same exact values, but both of them are negative (again, because both x and y are negative in quadrant 3). I can't see your choices but the one you want looks like this:

$(-\frac{\sqrt{3} }{2},-\frac{1}{2})$

Solve the rational equation:. x+3/3x-2 minus x-3/3x+2=44/9x^2-4

NISA [10]

$\frac{x+3}{3x-2} - \frac{x-3}{3x+2} = \frac{44}{9x^2-4}$
$\frac{(x+3)(3x+2) - (x-3)(3x-2)}{(3x-2)(3x+2)} = \frac{44}{(3x+2)(3x-2)}$

$(x+3)(3x+2) - (x-3)(3x-2) = 44$
$(3x^2 + 11x + 6) - (3x^2 - 11x + 6) = 44$
$22x = 44$
$x = 2$ Substituting x = 2 into the original does not give any extraneous solutions, so this is the answer.

3/8-1/4=?<br><br> Answer ……..

Vlad1618 [11]

Step 1: Find the LCD (Least Common Denominator)

The LCD between 4 and 8 is 8. Therefore, if I change all of the fractions to have a denominator of 8, the problem is as such:

3/8 - 2/8 = ?

Step 2: Subtract

3/8 - 2/8 = 1/8

Hope this helps!

Pat drank 1 1/3 cups of punch in the beginning of the party as she drank 2 and4/6 cups of punch at the end of the party.How much

SOVA2 [1]

Answer:

Pat drank 26/6 (4 1/3 or 13/3) cups of punch.

Step-by-step explanation:

Here is how I would solve this-

What is the question? How much punch did she drink in all?

What do we need to know? 11/3 + 4/6 cups of punch.

How can we make them have a common denominator? 22/6 + 4/6

Add them together! (22 + 4 = 26) so you get 26/6

Final Answer = Pat drank 26/6 (4 1/3 or 13/3) cups of punch.

Hope this helps! Good luck and let me know if this is right!

You have learned several methods for solving a system of equations. First, rank the methods in order of preference, noting which

kifflom [539]

Methods for solving a system of equations:
- elimination
- substitution
- augmented matrix

Ranks of method ( number one being the most preferred method)
1) elimination
2) substitution
3) augmented matrix

Elimination is my preferred method because it is simple and easy to work out and hard to get wrong.

Augmented matrix is my least preferred method because it is easy to get wrong and it requires complex steps to solve a simple equation.

Hope this helps ;)
