Answer:

It's C.

Step-by-step explanation:

A geometric sequence has a common ratio (r) where each term after the first is obtained by multiplying the previous one by r.

Checking through the list we see it is C because:

Second term 15 = first term * 5 = 3(5) = 15.

Third term = 15*5 = 75,

4th term = 75*5 = 375 and so on.

The common ratio is 5.

Solve the equation for x by graphing.

Answer:

Step-by-step explanation:

You literally just have to use a calc or solve it by yourself. Doesn't need a graph.

-2x + 3 = 3x - 2 (-3 and -x create positive)

-5x + 3 = -2 (subtract 3x from both sides)

-5x = -5

x= 1
