IF y varies inversely as x and y=10 when x=5 find y when x=25

y=k/x( where k is the constant)

10 = k/ 5

cross multiply

k= 50

so the relationship between x and y is

y= 50/x

when x is 25, y would be

y= 50/25

y= 2( final answer)

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.
