Direct Variation: If y = 6, when x = -2, find y when x = 18.

The answer is -54. Please mark as brainliest :)

Step-by-step explanation:

Y is directly proportional to x. So

y=kx

6=-2k

-3=k.

y=-3*18

y=-54.

10% of increase is the final answer! : )

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.
