Mr. lindsay wrote the four expressions below on the board.

expression one:
9 + 5x minus 5 + 3x
expression 2:
10x plus 3
expression 3:
x + 12
expression 4:
4(1+2x)

which expression is equivalent to 2x + 9 - x + 3? show your answer is correct by substituting a value for x.

i need a picure

step-by-step explanation:

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.
