You simply do it the same way as a positive number, just with a negative sign in front :)
Answer:
Step-by-step explanation:
∩ 
is asking for the intersection of sets 
and , or simply, which numbers can be found in both sets.
The numbers shared between the two sets are 
.
Next, we need to union this result with the set 
, or simply, combine the numbers in both sets together.
This would result in 
Answer:
b = -125/9
Step-by-step explanation:
1 + log5 ( -9b) = 4
Subtract 1 from each side
1 -1+ log5 ( -9b) = 4-1
log5 ( -9b) = 3
Raise each side to the base 5
5^ log5 ( -9b) = 5^3
This will cancel the log5
-9b = 125
Divide each side by 9
-9b/-9 = 125/-9
b = -125/9
Answer:
384 inches²
Step-by-step explanation:
The surface area of a cube is found by using 6a².
6 = the number of sides in a cube
a = the given dimension (in this case, 8 inches long)
SA = (6)8²
SA = 6(64)
SA = 384

Answer:
As 
approaches infinity 
approaches negative infinity.
Step-by-step explanation:
As you can see in the graph as grows larger in the negative direction, the 
increases in the negative direction too.
Thus:
