Use the drawing tool(s) to form the correct answer on the provided number line. eric wants to make sure he keeps an average speed of 70 miles/hour while testing his car’s engine. he allows the car’s speed to vary a certain number of miles/hour which can be modeled by the inequality |x − 70| ≤ 4. plot the range of speeds eric would not drive at under the given conditions.

  see below

Step-by-step explanation:

Eric will drive between 70 -4 = 66 mph and 70+4 = 74 mph. He will not drive less than 66 or more than 74 mph.

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)

your answer   is c
