1. ### Find K...MATH?

k^2 - 3k = 28 k^2 - 3k - 28 = 0 (k - 7)(k + 4) = 0 k = -4, 7 and if you're asked to find x: k = -4: -4 = (x + 3)/(x - 4) -4(x - 4) = x + 3 -4x + 16 = x + 3 16 - 3 = x...

2. ### Prove (n, k) = (n, n - k)?

... SOLUTION: I like to use this notation: C(n, k) = n! / [(n - k)! k!] That would mean: C(n, n - k) = n! / [(n...;--> {A, B, C} So C(n,k) = C(n, n-k)

3. ### find value of k for which y=6x+k is tangent to curve y=7sqrt(x.)?

... tangent lines of form y = 6x + k have slope 6  Set slope dy/dx = 7/[2√(x)] = 6  x = 49... how that applies here  (y/7)^2 = x = (y – k)/6  6y^2 = 49y – 49k  6y^2 - 49y + 49k = 0  49*49 = 4*6*49k...
