Answer:
The answer is one
Step-by-step explanation:
-9/12= -.75
-7/4= -1.75
-8,10 because it crosses the y axis
81.27 is the answer to 21% of 387 so a good estimate would be 82
The first step for solving this is to write the expression on the right side of the equation in exponential form.

Since the bases are the same,, set the exponents equal to each other.
x - 3 = -2
Now move the constant to the right side and then change its sign.
x = -2 + 3
Now calculate the sum to get your final answer.
x = 1
This means that the correct answer to your equation is going to be x = 1.
