The magnitude of an earthquake, r, can be measured by the equation r=log +d where a is the amplitude in
micrometers, tis measured in seconds, and d accounts for the weakening of the earthquake due to the distance from the
epicenter
if an earthquake occurred for 4 seconds and d = 2, which graph would model the correct amount on the richter scale?

p> q if you calculate p is100 q is 79

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
