What kind of system is the set of equations below? 2x -3y=6 2x+3y=2

a. Inconsistent -- no solution b. Dependent -- infinite number of solutions c. Consistent -- a single solution-add the equations: 4x = 8 x = 2 2(2) - 3y = 6 -3y = 2 y = -2/3 c. Consistent --a singl

Prove that lim as x goes to 0 of f(x) = 0 or lim as x goes to 0 of f(x)/x = 0

Suppose that f is a function that has the property that there is some M > 0 such that abs(f(x) -|f(x) - 0| = |f(x)| = 0 as x --> 0 it follows that f(x) --> 0. Furthermore, |f(x)/x| = 0) |f(x)/x| = 0
