The speed limit sign on the expressway says that the speed limit is 70mph. Write an inequality that represents all speeds you can legally drive on the expressway. x≥70x is greater than or equal to 70

x>70x is greater than 70

x≤70x is less than or equal to 70

x<70

the answer is 8/21

hope this

are ya tryin to ask something or is this a statement

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:
