The number f of miles a helicopter is from its destination x minutes after takeoff is given by f(x)=60-1.5x. The number f of miles a commercial jet is from its destination x minutes after takeoff is shown in the graph below

1. minimum

2. 6400

3. eight

hope this !

c

step-by-step explanation:

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :

you can do some additional rewriting here using the properties of the logarithm to simplify things if you like:

b is the right answer
