what does 13 k on earrings mean
200 k
If: y = x^2 -8x +7 and y = kx -2 Then: X^2 -8x +7 = kx -2 Transposing terms: x^2 +(-8x -kx) +9 = 0 Using the discriminant: (-8 -k)^2 -4(1*9) = 0 Expanding brackets: 64 +16k +k^2 -36 = 0 Collecting like terms: k^2 +16k +28 = 0 Factorizing the above: (k +2)(k +14) = 0 meaning k = -2 or -14 Therefore the possible values of k are: -2 or -14
try k mart :D
==> 3k+14=k ==>3k-k=-14 ==>2k=-14 ==>k=-7 ans...
k^2 for k > 1011^2, 12^2, 13^2, 14^2, ...121, 144, 169, 196, ...
What is the question ? Are you looking for the value of 'k' that makes the statement true ?It may be found as follows:-k - 6 - 7k + 20 = -2Clean up the left side:-8k + 14 = -2Multiply each side by -1:8k - 14 = 2Add 14 to each side:8k = 16Divide each side by 2:k = 2
-14
4k-7 = 7 4k = 14 k = 3.5 or k = 7/2
As there is no change in y, the perpendicular bisector is given by x = (10 + k)/2 This is given as x = 7; thus: → (10 + k)/2 = 7 → 10 + k = 14 → k = 4
Yes, 14 K has more gold that 10 K
