The function h is defined by h(x)=(20x−k)÷x+50, where k is a constant. find k, if the value of ℎ at x=20 is equal to 65. anyone who gets this right gets 50 i mean it oh and brainliest

The value of k is

Step-by-step explanation:

we know that

we have

substitute in the function and solve for k

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.

answer: -0.5 would be the most likley outcome
