Someone please help! I really don't get it, but it's multiple choice so hopefully that helps :)

1. b

2. c

3. B (nice font change)

4. D

5. D

6.C

Step-by-step explanation:

1. 5^2 = 3x+9

25 = 3x+9

x = 16/3

2. ln(x+2) = 5

Plugged in to desmos calculator, only e^5-2 is close to the graph of ln(x+2) = 5.

3. That's what logarithms are

4. 5 Units right is -5 because it's the opposite of what you would think, and it's inside the parenthesis.

6 units up is +6 outside of the parenthesis.

5. That's what logarithms are

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.
