X=-2 is the answer because

-4x=8 if you divide both sides by -4 you get x=-2

Divide both sides by -4.
-4x divided by -4x will be x
and 8 divided by -4x is -2
so x=-2
hope that helps

The cost of a regular price ticket to a Saint Louis Cardinal baseball game was $60. During the World

dezoksy [38]

1/5 of $60 is $12.

Therefore, 2/5 of $60 is $24.

If the price of tickets increased by 2/5 during the World Series, then during the World Series a ticket would've cost $60+$24=$84.

What is the value of f(x)=2•2^x for f(-2)

Zigmanuir [339]

Answer:

The value of f(-2) is 1/2 or it can be written as 0.5.

Step-by-step explanation:

The given function is

$f(x)=2\cdot 2^x$

We have to find the value of f(-2).

Substitute x=-2 in the given function to find the value of f(-2).

$f(-2)=2\cdot 2^(-2)$

$f(-2)=2\cdot \frac{1}{2^(2)}$

$f(-2)=\frac{1}{2}$

$f(-2)=0.5$

Therefore the value of f(-2) is 1/2 or it can be written as 0.5.
