Find the solution:<br> 3x + 2y = 12<br> -2x + 3y = 5
finlep [7]

Answer:

x = 3

y = 2

Step-by-step explanation:

3x + 2y = 12

-2x + 3y = 5 to find the solution we will use elimination method and for that, multiply second equation with 3 and the first equation with 2

<em>2 * 3x + 2y = 12</em>

<em>6x + 4y = 24</em>

<u>3 * -2x + 3y = 5</u>

<u>-6x + 9y = 15</u>  now find the sum of both equation:

<em>6x + 4y  </em><u>-6x + 9y</u> = 24 + 15 add like terms

13y = 39 divide both sides by 13

y = 3 now that we found the value of y we can use this to calculate the value of x

3x + 2y = 12 replace y with 3

3x + 2*2 = 12

3x + 4 = 12 subtract 4 from both sides

3x = 9 divide both sides by 3

x = 3

Verify the identity and explain how cot(x- pi/2)= -tan x
pav-90 [236]

Answer:

First, let's recall some usefull information:

- cot(x) = 1/tg(x) = cos(x)/sin(x)

- tan(x) = sin(x)/cos(x)

We also know that:

- cos(x - pi/2) = sin(x)

- sin(x - pi/2) = -cos(x)

Now we can use those relationships and get:

cot(x - pi/2) = cos(x - pi/2)/sin(x -pi/2) = sin(x)/-cos(x) = -tan(x)

So we have verified the identity, and explained step by step why the identity is true.

Your realized income from your primary job is $3,076.45/month. Your fixed expenses are 36% of your realized income. How much mus
erastovalidia [21]
If you would like to know how much money you must save for an emergency fund of 6 months, you can calculate this using the following steps:

36% of $3,076.45 = 36% * 3,076.45 = 36/100 * 3,076.45 = $1,107.522

6 months * $1,107.522 = 6 * 1,107.522 = $6,645.132

The correct result would be $6,645.132.
