3x+4y+6z=15<br>Solve for x.​
aalyn [17]

Answer:

<h2> </h2><h2>x = 5 -  \frac{4}{3} y - 2z</h2>

Step-by-step explanation:

<h3><u>Question</u><u>:</u><u>-</u></h3>
  • To solve for x

<h3><u>Equation</u><u>:</u><u>-</u></h3>
  • 3x + 4y + 6z = 15

<h3><u>Solution</u><u>:</u><u>-</u></h3>

=> 3x + 4y + 6z = 15

  • <em>[</em><em>On</em><em> </em><em>subtracting</em><em> </em><em>both</em><em> </em><em>sides</em><em> </em><em>with</em><em> </em><em>4y</em><em>]</em>

=> 3x + 4y + 6z - 4y = 15 - 4y

  • <em>[</em><em>On</em><em> </em><em>Simplification</em><em>]</em>

=> 3x + 6z = 15 - 4y

  • <em>[</em><em>On</em><em> </em><em>subtracting</em><em> </em><em>both</em><em> </em><em>sides</em><em> </em><em>with</em><em> </em><em>6z</em><em>]</em>

=> 3x + 6z - 6z = 15 - 4y - 6z

  • <em>[</em><em>On</em><em> </em><em>Simplification</em><em>]</em>

=> 3x = 15 - 4y - 6z

  • <em>[</em><em>On</em><em> </em><em>dividing</em><em> </em><em>both</em><em> </em><em>sides</em><em> </em><em>with</em><em> </em><em>3</em><em>]</em>

=  >  \frac{3x}{3}  =  \frac{15 - 4y - 6z}{3}

  • <em>[</em><em>On</em><em> </em><em>Simplification</em><em>]</em>

=  > x = 5 -  \frac{4}{3} y - 2z \: (ans)

Which simplifications of the powers of i are correct?
OleMash [197]

The correct simplifications of powers of i are:

a. i^27=−i

d. i^8=1

e. i^5=i

Step-by-step explanation:

We know that

i^2=-1\\i^3=-i\\i^4=1

We can use the smaller powers of i to solve the larger powers.

a. i^27=−i

i^{27}\\={i^{24}}.i^3\\={i^{4*6}}.-i\\=(i^4)^6.-i\ \ \ \ As\ we\ know\ i^4=1\\=(1)^6.-i\\=1*-i\\=-i

b. i^28=i

i^{28}\\=i^{4*7}\\=(i^4)^7\\=(1)^7\\=1

c. i^14=1

i^{14}\\=i^{12}.i^2\\=(i^{4*3}).i^2\\=> i^2=-1\\=(i^4)^3.-1\\=(1)^3*-1\\=-1

d. i^8=1

i^8\\=i^{4*2}\\=(i^4)^2\\=(1)^2\\=1

e. i^5=i

i^5\\=i^{2*2*1}\\=i^2*i^2*i\\=(-1)(-1)(i)\\=i

Hence,

The correct simplifications of powers of i are:

a. i^27=−i

d. i^8=1

e. i^5=i

What is the value of x
Advocard [28]

According to the properties of parallelograms the diagonals bisect each other. What this means is that each "half" of a diagonal is equal to each other. With this in mind you can set each half equal to each other in an equation like so...

3x + 3 = 6x - 57

Now you must combine like terms

60 = 3x

Isolate x by dividing 3 to both sides

60/3 = 3x/3

20 = x

Hope this helped!
