Answer:
55
Step-by-step explanation:
make each mixed number an improper fraction:
8 1/4 = 33/4 6 2/3 = 20/3
then multiply these two improper fractions:
660/12
and lastly simplify!!
ANSWER: 55
(2 / x-1)> (7 / x + 1)
For this case we can solve the problem graphically.
The solution will be the shaded region.
Note: see attached image.
Answer:
The solution is given by:1 <x <9/5
Answer:
Step-by-step explanation:
Jen: (1+2/3)x4 to find average (multiply by 4 to get 1 hour)
Jen's ave. is 3+2/3 mph
Max: (1.5)x5= average
Max's is 9 mph
Max is faster.
Using it's concepts, we have that:
- The domain of the relation is of -2 ≤ x ≤ -1.
- The range of the relation is of -2 ≤ y ≤ 2.
- Since each value of the input is mapped to only one value of y, it is a function.
<h3>
What are the domain and the range of a relation?</h3>
- The domain of a relation is the set that contains all possible input values for the relation. In a graph, it is given by the values of x.
- The range of a relation is the set that contains all possible output values for the relation. In a graph, it is given by the values of y.
Hence:
- The domain of the relation is of -2 ≤ x ≤ -1.
- The range of the relation is of -2 ≤ y ≤ 2.
<h3>When does a relation represents a function?</h3>
A relation represents a function when each value of the input is mapped to only one value of the output.
From this graph, we have that <u>each value of x is mapped to only one value of y</u>, that is, there are no vertically aligned points, hence the relation is a function.
