If you're talking about (K-0)=1, then the answer is most definitely 1.

That depends what the values of k and b are.

Using the discriminant for a quadratic equation the value of k works out as plus or minus 12.

2k = 5k-30 Subtract 5k from both sides: -3k = -30 Divide both sides by -3 to find the value of k remembering that a minus divided into a minus becomes a plus: k = 10

No.

If you're talking about (K-0)=1, then the answer is most definitely 1.

k=.81 17 times over then, 82

That depends what the values of k and b are.

31 = 3-4k 31-3 = -4k 28 = -4k Divide both sides of the equation by -4 to find the value of k: k = -7

k - k = 0

Using the discriminant for a quadratic equation the value of k works out as plus or minus 12.

x2y = k (constant) so 36 x 2 ie 72 is the constant. If x = 3 then y = 72/9 = 8

2k = 5k-30 Subtract 5k from both sides: -3k = -30 Divide both sides by -3 to find the value of k remembering that a minus divided into a minus becomes a plus: k = 10
