Given f(x) = x^2 + kx -15, and the remainder when f(x) is divided by x-2 is -23, then what is the value of k?

k=-6

Step-by-step explanation:

f(2)=-23, 4+2k-15=-23. 2k=-12. K=-6

the answer is 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.
