Write an exponential equation in the form y = abx whose graph passes through points (−3, 24) and (−2, 12). y = 3x y = 3(0.5)x y
Bingel [31]

Answer:

Option B.

Step-by-step explanation:

The given exponential equation is

y=ab^x  ...(1)

It is given that the graph of above equation passes through points (−3, 24) and (−2, 12).

The graph passes through the point (-3,24), so substitute  x=-3 and y=24 in equation (1).

24=ab^{-3}   ...(2)

The graph passes through the point (-2,12), so substitute  x=-2 and y=12 in equation (1).

12=ab^{-2}   ...(3)

Divide equation (3) by equation (2).

\dfrac{12}{24}=\dfrac{ab^{-2}}{ab^{-3}}

0.5=b

Substitute b=0.5 in equation (2).

24=a(0.5)^{-3}

24=\dfrac{a}{(0.5)^{3}}

24=\dfrac{a}{0.125}

24\times 0.125=a

3=a

Substitute a=3 and b=0.5 in equation (1).

y=3(0.5)^x

Therefore, the correct option is B.

How do I find the complement?
likoan [24]

Let A be some subset of a universal set U. The "complement of A" is the set of elements in U that do not belong to A.

For example, if U is the set of all integers {..., -2, -1, 0, 1, 2, ...} and A is the set of all positive integers {1, 2, 3, ...}, then the complement of A is the set {..., -2, -1, 0}.

Notice that the union of A and its complement make up the universal set U.

In this case,

U = {1, 2, 3, 6, 10, 13, 14, 16, 17}

The set {3, 10, 16} is a subset of U, since all three of its elements belong to U.

Then the complement of this set is all the elements of U that aren't in this set:

{1, 2, 6, 13, 14, 17}

The correct answer is B.
\frac{7}{6}
is greater then one, 9/10 is only slightly less than one, 2/3 is a little more than half, and 1/8 is the smallest number.
