what is the value of sin(83 degrees) to the nearest ten thousandth
OpenStudy (skittles_for_life6422):
@Smart_girl3 here is the new question
OpenStudy (skittles_for_life6422):
hey
OpenStudy (skittles_for_life6422):
do you know how to do this
OpenStudy (anonymous):
sine(83 deg)=0.992546151641322
i think this is right

i can try XD
OpenStudy (skittles_for_life6422):
\[\frac{ 1 }{ 2x+14 }-\frac{ 9 }{ x+7 }=-6\]
OpenStudy (anonymous):
hmm i haven't done that in a while
OpenStudy (skittles_for_life6422):
yeah me 2
OpenStudy (anonymous):
im sorry i dont know that one but i can try and get the answer from someone else

*not
OpenStudy (owlcoffee):
so we have:
\[\frac{ 1 }{ 2x+14 }-\frac{ 9 }{ x+7 }=-6\]
this is what we call a "rational function" because we can see an "x" in the denominator.
but it is a "rational equality" because there is an equal sign that makes it equal to a constant or another function.
so, we have to solve that fraction and make it all a single fraction, wich is easier to solve.
In order to do that, we will multiply the second by a common factor of the denominator of the first, wich is visible "2", so therefore:
\[\frac{ 1 }{ 2x+14 }-\frac{ 18 }{ 2x+14 }=-6\]
now that they have the same denominator we can associate the whole fraction into a single one:
\[\frac{ 1-18 }{ 2x+14 }=-6\]
\[\frac{ -17 }{ 2x+14 }=-6\]
and now, let's multiply by the denominator on both sides of the equation:
\[(2x+14)\frac{ -17 }{ (2x+14) }=-6(2x+14)\]
\[-17=-12x-84\]
\[64=-12x\]
\[x=-\frac{ 64 }{ 12 }\]
OpenStudy (skittles_for_life6422):
ok that makes a lot of sense thank you can i ask some more questions
OpenStudy (michele_laino):
sorry I was considering the first question about sin(83) @skittles_for_life6422
OpenStudy (skittles_for_life6422):
its ok
