Could someone please help me with this. I am confused. Math is a weak point for me. Solve the system of equations by graphing. Then classify the system. 9x-6y=30, 6x-9y= -30. The solution is? Consistent or inconsistent, dependent or independent? How would I graph this? Thanks.

guess and check on finding the middle term (it's 9) to get 18 terms mathematically I thought you were supposed to log both sides log156.25 = log(.1024*2.5)^n-1 log156.25 = n-1log(.256)<--power of log rule log156.25/log(.256) =n-1 I did something wrong though... because my ...

Your calculator gives an answer of x=1.1578074156, y=2E-13 when using ROOT or ZERO in the graphing mode. Give the coordinates of the x-intercept your calculator has given you to the nearest thousandth. <<< ? I have no idea how to solve these. Someone please explain ...

2E-13 on most calculators means 2.0 x 10^-13 which for all practical purposes is zero. 1.15780.. to the nearest thousandth is 1.158 So what is the x-intercept ?

if f(x) = (x/7)-3 find f^-1(x) I'm completely lost! Help
Tuesday, August 24, 2010 at 2:00am by Janie
The inverse function f^-1(x) gives you back x when you input y = f(x) as the independent variable. Start with y = (x/7)-3 y + 3 = x/7 x = 7y + 21 Since you are using x as the independent variable of the inverse function, you have to switch x and y in the equation above. The ...
