Your answer should be B. Two sets are equal if they contain the same elements. Two sets are equivalent if they have the same cardinality or the same number of elements.
Domain ( all possible values of x) is x > 5 or in interval notation it is (5, ∞)
The range( all possible values of log x) is (-∞, ∞)
F. Buying 4 bottles of Fresh All.
Answer:
it can either be written as x > -1 and x < 2 or as -1 < x < 2.
Step-by-step explanation:
The graph of a compound inequality with an "and" represents the intersection of the graph of the inequalities. A number is a solution to the compound inequality if the number is a solution to both inequalities. It can either be written as x > -1 and x < 2 or as -1 < x < 2.
4^(12-4x)=256 realize that 256 is 4^4 so we really have:
4^(12-4x)=4^4 taking the natural log of both sides
(12-4x)ln4=4ln4 dividing both sides by ln4
12-4x=4 subtract 12 from both sides
-4x=-8 divide both sides by -4
x=2
