The higher the pH the more basic something is. Water is generally around pH 7 (calculated using logarithms)

Also, in seismology. <span>Vibrations are picked up and plotted on a seismograph. The strength, or magnitude, of an earthquake is measured using the Richter scale. The Richter scale is numbered 0-10.
</span><span>
</span><span>So an earthquake thats a 5 on the Ricter scale is 10 times stronger/bigger than one that's a 3. (Logarithms)

Given the function f(x) = -5x + 1 + 3, for what values of x is f(x) = -12?
irina1246 [14]

Answer:

x=\frac{16}{5}

Step-by-step explanation:

The given function is

f(x) = -5x +1+3

Which can be rewritten also as

f(x) = -5x +4

We want to find the values of x for which

f(x) = -12

In order to do that, we just substitute -12 into f(x), and we solve the equation for x:

-12 = -5x + 4\\-16 = -5x\\x=\frac{-16}{-5}=\frac{16}{5}
