  • What smart phone is best to flash to Metro PCS?

    I wanted to get an Iphone 4 but after researching the results I have found that there is no mms or internet access and also that you are more likely to not have service in many areas opposed to using a regular Metro phone. So I want to know if there are other smart phones that are really good but can also be flashed to use Metro PCS that will allow me to use internet and receive picture messages with the ability to text and call others out of state.

  • how would I solve for x in these problems? (Logarithmic problems)?

    I have been working on my homework all night and I am stuck on three problems, these two are giving me a really hard time. I wish to understand how they are solved so I can solve similiar problems on the practice sheet. So here they are, please explain the process.

    log base 8(x)+log base 8(x+2)=1

    and

    5=3^x-1

    I have no idea on how to even start these problems.

  • Math word problem troubles (logarithmic functions)?

    so the questions is:

    the number of gallons of ethanol produced in the U.S. can be estimated by E(t)=0.18(1.137)^t

    where E(t) is the annual production, in the billions of gallons, "t" years after 1980

    a) in what year did the U,S, produce 5 billion gal of ethanol?

    b) In what year will the U.S. produce 25 billion gal of ethanol?

    What the example in the book said to do is substitue 5 billion with E(t) so the equation would look like this:

    5,000,000,000= .18(1.137)^t

    is that correct? I did the math and I ended up with 187.5 which would mean that the U.S. reached 5 billion in the year 2167 (187.5 years+ 1980) which is obviously not correct, how do i tackle this questions?

  • How would I graph this?

    3x+4y<12 ends up to

    y<12-3x (right?)

    Now I dont understand how I can plot anything that resembles y<3x+12 or anything of that sort. Teach me how to math! (Yup I understand math is not verb)

  • Is my answer correct?

    The problem was 2x-1>5 and 2-3x>11

    And I proceeded to do this.

    2x>6 -3x>9

    x>3 and x<-3

    so

    {x|x>3} Disjoint {x|x<-3}

    Am I correct?

  • How I do elimination using matrices?

    Ok so my problem is this.

    x+2y-3z=9

    2x-y+2z=-8

    3x-y-4z=3

    so then I turn it into a matrix right?

    so

    1 2 -3|9

    2-1 2|-8

    3-1-4|3

    now then I am getting confused once I get to

    1 2 -3|9

    0 -5 8|-26

    0 -7 9|-24

    Am I allowed to add to any row, because if so it would make it easy but I doubt I can. so how do I continue after this? from my understanding I am only allowed to interchange any two rows, multiply all elements of a row by a non zero constant and replace a row with the sum of that row and a multiple of another row. So honestly I do not under stand how I can multiply two with a non zero constant to be able to cancel out one of the numbers.Or am I wrong on so far what I have? Please help.
