THIS IS FOR ALGEBRA/PRE-CALCULUS MATH. I POSTED IT JUST AS THE TEACHER WROTE IT.

pre calculus
You need to write out the question. I have no idea what "pre calculus" this could be, maybe zeroes, however, that is standard fare for an algebra course.

pre calculus
Pre-Calculus? I wonder what the question is. In a basic algebra course, you would be looking for zeroes, and probably get those by factoring. 2x^2+11x-21=0 (2x-3)(x+7)=0 x= 1.5, or x=-7

Algebra 2
In Kentucky, where i am from, we do algebra and algebra two before pre-cal and calculus. I didnt realize that the problem could be solved in multiple ways and i apologise. But the solution should be done without calculus.

I am too embarassed to ask this Calculus (really pre-calculus) question in tutoring, because I know I should know. Is the inverse of f(x)=3x-1 actually f(x)=1/3x+1? How do I find it? What if it asks the same equation replaced with f to the -1 power (x)? I think I know how the ...

what does pre-algebra mean??
Pre-Algebra is basically preparing you for Algebra. Pre-Algebra teaches you Order of Operations, Properties of Numbers, Rational and Irrational Numbers, Exponents, PEMDAS, ect.

Pre calculus? This is stock Algebra II. put the equations in the form of ax^2+bx+c=0 then factor. for instance, c is already in that form. 2x^2+x-6=0 (2x-3)(x+2)=0 x= 3/2 x=-2 do the others the same method.

Are you doing pre-calculus or calculus? In calculus, the maximum is obtained by setting f'(t)=derivative with respect to t = 0 and solving for t. In pre-calculus, you can transform the expression by completing the squares. Ax² + Bx + C =A(x²+ (B/A)x + C/A) =A((x + (B...

well, shoot. Then just subtract 8 from both sides to get 3x^2 = -12 x^2 = -4 there is no real solution, since x^2 is never negative for real x. If you allow complex solutions, then x = 2i or -2i. I believe this is from Algebra I, and should not be posing a difficulty for ...

Math: Pre-calculus
P=2(W+L) A=WL, so L = 180/W so, P = 2(W+180/W) This is pre-cal, so you don't have calculus at your disposal. But, you do know that a square has maximum area for a given perimeter. So, W = L = √180 = 6√5

You have titled the post "algebra 2". Does that mean that you have done calculus, or should the solution be without calculus? We usually solve maximization problems by linear programming or calculus. However, this problem can also be solved by tabulation without using calculus...

The "dx" at the end makes me think you are supposed to integrate [e^-x / e^-1] + 3 . But that would make it a calculus, not a precalculus, question. It is not clear what the question is. In any case, e^-x / e^-1 = e^(1-x) The integral of e^(1-x) + 3 dx is -e^(1-x) + 3x + C
