You can put this solution on YOUR website! yx=k.......eq 1
:
5(20)=k
:
k=100
:
now that we know k we can write a formula. plugging in 100 for k in equation 1
:
xy=100---now we are given y(2) and want to solve for x
:
remember in an inverse relationship if one variable decreases the other increases and vice versa. Since y is decreasing we will expect that x will increase
:
x(2)=100
: sure enough, x increased going from 20 to 50
