Answer:

z =0.001

Step-by-step explanation:

log z + 12 = 9

Subtract 12 from each side

log z + 12-12 = 9-12

log z = -3

Raise each side to the base of 10

10^ log z = 10 ^-3

z = 10 ^-3

z =0.001

Answer:

Quadratic Equations! Yes!

Step-by-step explanation:

Now, there are three methods to solving this:

1.Quadratic Formula

2.Factoring

3. Completing the square

Now, Based on the answers, I think it would be better if we used Quadratic Formula, as you cannot get the answer easily with factoring, and I'm a bit rusty on completing the square.

So, Quadratic Formula! To solve it using this method, we have to find x using this: $x=\frac{-b+-\sqrt{b^{2} -4ac} }{2a}$ (the +- before the square root means it could be both positive or negative)
