I really dont need the answer, I just need someone to explain this a little more to me...14 + 2 l3x + 5l = 25(Solving for X). I came up with x = 1/3 but my teacher told me it was wrong.... Thank you.

Write an equation for the line that passes through the points (0, -6) and (-3, 0).

Help y = -2x - 6 y = -2x - 3 y = -1/2x - 6 y = -1/2x - 3-The general form of a linear equation is y = mx + b, where m is the slope and b is the y-intercept. So, substituting the given (x,y) points, y

Find the series solutions of the differential equation

Assume x>0 Find the series solutions of 2xy+y+xy=0 around the point 0.-Since x = 0 is a regular singular point, assume that y = Σ(n = 0 to ∞) a(n) x^(n+r). Substituting this into 2xy + y + xy = 0 yie

Help me find the domain of this log function

212. I need to find the domain of f(x) = log(3x-x^2).... I know it would be the inverse of 10^(3x-x^2).... I think? Ah! Help, explain how I would go about figuring this out... thanks---- You can only

How would you solve for the sum of this series? Summation from n=3 to infinity (3^(n+3))/(5^(n-3))

I dont understand how to go about solving this. Any help would be greatly appreciated!!! Thank you!-By the laws of exponents, you can write: (a) 3^(n + 3) = 3^n * 3^3 = 27(3^n) (b) 5^(n - 3) = 5^n *
