To complete the square, begin by grouping the `x^2` and `x` terms: `(-3x^2 +6x)-4` Now factor out the `-3` `-3(x^2-2x)-4` The formula you need now is `(b/2)^2` . In this case, that is `(-2/2)^2` which equals `1` . You must both add and subtract it from the problem, so as not to change its value. The trick is that `1` which is added inside the parentheses is being multiplied by a distributed `-3` . Therefore, you are not really adding `1` ,...http://www.enotes.com/homework-help/whats-complete-squate-3x-2-6x-4-my-answer-books-477484Fri, 24 Apr 2015 18:06:36 PSTEvery triangle we make in the unit circle will be a right triangle.

Every triangle we make in the unit circle will be a right triangle. But x is not the right angle. It will look something like the picture below. *note how this will work for any angle theta* So we use the pythagorean theorem where sin(theta)=y and cos(theta)=x to make: `sin^2(theta) + cos^2(theta) = 1`http://www.enotes.com/homework-help/identity-sin2-x-cos2-x-1-x-only-right-triangles-477883Fri, 24 Apr 2015 17:52:32 PSTYour questions deal with the concept of % changes or increase/decrease %...

Your questions deal with the concept of % changes or increase/decrease % (or inflation/discount). In all such case, new cost (or price) = old cost (or price) + old cost (or price) x % change remember that positive change or increase is given by a positive sign and a discount or decrease by a negative sign. I will solve just a couple of your questions to give you the idea and hopefully thy will help you get through the rest on your own... 1)...http://www.enotes.com/homework-help/help-me-please-477908#1Fri, 24 Apr 2015 17:46:51 PSTIf the question referred to .36, without repetition, it would be...

If the question referred to .36, without repetition, it would be 36/100. However, since it repeats, it is referring to 36/99. [If there are n repeating digits, write the part that repeats over n nines. In this case, there are 2 repeating digits, so we write them over 2 nines.] That can be simplified to 4/11. You would then multiply 4/11 * 11/2. The 11s will cancel, leaving you with 4/2, which is just 2.http://www.enotes.com/homework-help/what-value-36-repeating-11-2-without-using-477504Fri, 24 Apr 2015 17:45:48 PSTStart by writing any missing number as a variable.

http://www.enotes.com/homework-help/pls-help-dont-understand-477896
Start by writing any missing number as a variable. If “The numerator of the fraction is five less than the denominator,” then you could write the denominator as x and the numerator as x-5. That means that the missing fraction is (x-5)/x. Now you must “add one to the numerator and denominator.” So the new fraction is (x-5+1)/9x+1) or (x-4)/(x+1). According to the question, this equals 2/3. Therefore, we can set up an equation:...http://www.enotes.com/homework-help/pls-help-dont-understand-477896Fri, 24 Apr 2015 17:37:03 PSThelp me please

Suppose the denominator is x, then the numerator is x-5, since numerator is 5 less than denominator. And the required fraction is (x-5)/x If we use the given scenario, when 1 is added to the numerator and denominator , the fraction becomes 2/3 Adding 1 to both numerator and denominator: (x-5+1)/(x+1) = 2/3 or 3 (x-4) = 2(x+1) or 3x-12 = 2x+2 or 3x-2x = 2+12 that is x =14 and x-5 = 9 Thus the required fraction (x-5)/x = 9/14. check: adding...http://www.enotes.com/homework-help/pls-help-dont-understand-477896#3Fri, 24 Apr 2015 09:46:47 PSTThe numerator of a fraction is 5 less than its denominator.

I asked the question. Sorry, that second answer by me was posted in haste and has a typo. I meant "therefore by definition, it is only for right triangles" (not right "angles"), because sine or cosine are only defined for right triangles, and not for any triangle.http://www.enotes.com/homework-help/identity-sin2-x-cos2-x-1-x-only-right-triangles-477883#5Fri, 24 Apr 2015 08:51:37 PSTI asked the question.

I asked the question. However, I believe the first answer is in error as follows. sine is the ratio of the length of the opposite side to the length of the hypotenuse. In our case, it does not depend on the size of the particular right triangle chosen, as long as it contains the angle A, since all such triangles are similar. Therefore by definition, it is only for right angles.http://www.enotes.com/homework-help/identity-sin2-x-cos2-x-1-x-only-right-triangles-477883#6Fri, 24 Apr 2015 07:51:10 PSTThe system of equations -3x + y = -7 and 5x - 2y = 12 has to be solved....

The system of equations -3x + y = -7 and 5x - 2y = 12 has to be solved. From the first equation -3x + y = -7 we can express y in terms of x, y = 3x - 7. Substitute for y in 5x - 2y = 12 5x - 2(3x - 7) = 12 5x - 6x + 14 = 12 -x = -2 x = 2 y = 6 - 7 = -1 The solution of the given system of equations is x = 2 and y = -1http://www.enotes.com/homework-help/3x-y-7-5x-2y-12-solve-system-using-substitution-476861Fri, 24 Apr 2015 05:27:21 PSTThe system of equations 3x - y = 4 and 5x + 3y = 9 has to be solved...
http://www.enotes.com/homework-help/3x-y-4-5x-3y-9-solve-system-using-substitution-476870
The system of equations 3x - y = 4 and 5x + 3y = 9 has to be solved using the substitution method. From the first equation 3x - y = 4 we can express y in terms of x as y = 3x - 4. Substitute this for y in the second equation 5x + 3y = 9. This gives: 5x + 3(3x - 4) = 9 5x + 9x - 12 = 9 14x = 21 x = 21/14 y = 3*(21/14) - 4 = 1/2 The solution of the given system of equations is x = 21/14 and y = 1/2http://www.enotes.com/homework-help/3x-y-4-5x-3y-9-solve-system-using-substitution-476870Fri, 24 Apr 2015 05:24:14 PST
