Answer:

quotient-----4

Remainder---1

Step-by-step explanation:

This is basic division am I right?

Opposite of division is Multiplication

Multiplication is repeated addition

4+4+4+4=16

16+4=20 but that is greater than 17.

so quotient is 4 and remainder is 1

What is the solution of the system of equations? 6x-2y = 4 -9x+3y = 12

katrin2010 [14]

We will have the following:

First, we solve both equations for y, that is:

$6x-2y=4\Rightarrow-2y=-6x+4$ $\Rightarrow y=3x-2$

$-9x+3y=12\Rightarrow3y=9x+12$ $\Rightarrow y=3x+4$

From this we can see that they are parallel lines, that do not share any common points, so there is no solution for the system.

Please help i beg i never get these right

Answer:

$\sin(105) = \frac{\sqrt 2 + \sqrt 6}{4}$

Step-by-step explanation:

Given

$\sin(105^o)$

Required

Solve

Using sine rule, we have:

$\sin(A + B) = \sin(A)\cos(B) + \sin(B)\cos(A)$

This gives:

$\sin(105^o) = \sin(60 + 45)$

So, we have:

$\sin(60 + 45) = \sin(60)\cos(45) + \sin(45)\cos(60)$

In radical forms, we have:

$\sin(60 + 45) = \frac{\sqrt 3}{2} * \frac{\sqrt 2}{2} + \frac{\sqrt 2}{2} * \frac{1}{2}$

$\sin(60 + 45) = \frac{\sqrt 6}{4} + \frac{\sqrt 2}{4}$

Take LCM

$\sin(60 + 45) = \frac{\sqrt 6 + \sqrt 2}{4}$

Rewrite as:

$\sin(60 + 45) = \frac{\sqrt 2 + \sqrt 6}{4}$

Hence:

$\sin(105) = \frac{\sqrt 2 + \sqrt 6}{4}$
