Which simplifications of the powers of i are correct? There may be more than one correct answer.
fredd [130]

\bf i^2=-1\qquad\qquad i^3=-i\qquad \qquad i^4=1 \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ i^{22}\implies i^{(4\cdot 5)+2}\implies i^{4\cdot 5}i^2\implies (i^4)^5 i^2\implies 1^5(-1)\implies -1~\dotfill \bigotimes \\\\\\ i^{11}\implies i^{(2\cdot 5)+1}\implies (i^2)^5 i\implies (-1)^5(i)\implies -i~\dotfill \checkmark

\bf i^{21}\implies i^{(4\cdot 5)+1}\implies (i^4)^5 i\implies 1^5(i)\implies i~\dotfill \checkmark \\\\\\ i^{12}\implies i^{3\cdot 4}\implies i^3 i^4\implies (-i)(1)\implies -i\dotfill \bigotimes \\\\\\ i^{20}\implies i^{4\cdot 5}\implies (i^4)^5\implies 1~\dotfill \checkmark \\\\\\ i^{26}\implies i^{(4\cdot 6)+2}\implies (i^4)^6 i^2\implies 1^6(-1)\implies -1\dotfill \checkmark \\\\\\ i^{27}\implies i^{(4\cdot 6)+3}\implies (i^4)^6 i^3 \implies 1^6(-i)\implies -i\dotfill \bigotimes

For the following system, if you isolated x in the first equation to use the substitution method, what expression would you subs
alekssr [168]

Answer:

x=2y+6

Step-by-step explanation:

So we have the system:

-x+2y=-6\\3x+y=8

If we isolate the x-variable in the first equation:

-x+2y=-6

Subtract 2y from both sides:

-x=-6-2y

Divide both sides by -1:

x=2y+6

Therefore, we would substitute the above into the second equation:

3x+y=8\\3(2y+6)+y=8

The answer is 2y+6

Further notes:

To solve for the system, distribute:

6y+18+y=8

Simplify:

7y+18=8

Subtract:

7y=-10

Divide:

y=-10/7\approx-1.4286

Now, substitute this value back into the isolated equation:

x=2(-10/7)+6\\x=-20/7+42/7\\x=22/7\approx3.1429
