3 people wearing both are also counted in the 6 with socks and 4 with shoes so you can't count them twice. What you do in stead is list :
<span>3 wearing both </span>
<span>4 - 3 = 1 wearing just shoes </span>
<span>6 - 3 = 3 wearing just socks </span>
<span>total 7 so far so that leaves 5 others that must be barefoot.</span>
Answer:
3 hours

Answer:
-13/20
Step-by-step explanation:
-4/5 x 4/4 = -16/20
3/20 x 1/1 = 3/20
-16/20 + 3/20 = (-16 + 3 = -13)
-13/20
Given:
The logarithmic equation is:
To find:
The exponential equation for the given logarithmic equation.
Solution:
We have,
It can be rewritten as:
Using 
, we get
Therefore, the correct option is C.
Answer:
The inverse of
y
=
2
x
is
y
=
log
2
x
Explanation:
This is how to do it.
From the given
y
=
2
x
interchange the variables so that
x
=
2
y
then solve for y:
x
=
2
y
take the logarithm of both sides with base
=
2
log
2
x
=
log
2
2
y
log
2
x
=
y
and
y
=
log
2
x
The graph of
y
=
2
x
and its inverse
y
=
log
2
x
. They are symmetric with the line
y
=
x
graph{(y-2^x)(y-log x/log 2)(y-x)=0[-20,20,-10,10]}
