3^(x−1) = 27
I need the answer please and thanks

x=2

Step-by-step explanation:

For the given equation

To find the value of x which is in power of base 3, make the base of R.H.S also 3

Making 27 in the power of three will be written as:   27=

So,                    

Now, we have same base on both the sides, so we can equate their powers of R.H.S and L.H.S.

So, for the equation, the value of x is 2

answer: c, the green line

step-by-step explanation:

there is no black line, eliminate b.

simple interest implies periodic payments, but the red line shows no payments, eliminate d.

simple interest has equal payments. if paid say every day, the graph is about a straight line (actually a stairstep).

the yellow line is not straight, eliminate a.

check: the green line is straight, answer is c.

simple interest with positive interest rate gives a straight line sloping up to the right. green line:

g(t) = $100 + ($200-$100) ÷ (20 years) × (t years)

= $100 + (4%/year) × ($100)(t years)

incidentally, the yellow line curving upward represents continuously compounded interest

y = $100 × 2^(t years / (14 assuming the yellow line hits $200 at 14 years. 2^0 is 1, so y(0) = $100; 2^(14/14) is 2, so y(14) = $200.
