If y varies directly as x and y = 36 when x = 4,what is the value of y when x=6?​

x=-7 When we say a variable varies directly with another variable, that is another way of saying that if the first variable increases, the second variable increases and vice-versa.

Step-by-step explanation:

we don't have enough info to solve this

b. 6

step-by-step explanation:

we are given the table representing an exponential function.

we can see from the table that, as x is increasing, the value of y is increasing in the power of 6.

i.e. the following relation is obtained,

x = 1, y = 6

x = 2, y = 36 =

x = 3, y = 216 =

x = 4, y = 1296 =

x = 5, y = 7776 =

so, the geometric series obtained is .

thus, the common ratio is given by = = 6.

hence, the common ratio is 6.
