3x+ (-5y)= 12 what are the values of a, b,& c?

a=3

b=(-5)

c=12

5   1/4   miles per hour

step-by-step explanation:

15   3/4 / 3 = 5   1/4

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.
