Answer:
The given relation
is a function.
Step-by-step explanation:
A relation
is given.
It is required to determine whether the given relation is a function.
To determine whether the given function is a relation, identify the domain and range and then check whether the given relation is a function.
Step 1 of 1
The given relation is {(a, b),(c, d),(e, d)}.
The set of the first components of each ordered pair is called the domain.
From the relation, the domain is {a, c, e}.
The set of the second components of each ordered the range.
From the relation, the range is {b, d, d}.
The given relation is a function. But it is not a one-to-one function.
Answer:
$20.85 less.
Step-by-step explanation:
City sales:
7% tax = 48.65
total bed cost = $743.65
Nearby City:
4% tax = 27.8
total bed cost = $722.8
city sale - nearby city
743.65 - 722.8
=20.85
Answer:
Yes, x and y have a proportional relationship.
Step-by-step explanation:
A proportional relationship means that, when comparing two quanities, that they are both changing at a constant (same) amount. When looking at a table to compare quantities, you can see that the pounds of tomatoes 'x' is increasing by one (1) each time. If you look at the amount spent in dollars 'y', you can see that for each pound (x), the cost is increasing by $4. So, since for every pound of tomatoes that is purchased increases by $4, then their relationship is proportional.
Step-by-step explanation:
<em>x</em><em> </em><em>=</em><em> </em><em>5</em><em>1</em><em>.</em><em>5</em>
<em>I'm </em><em>am </em><em>not </em><em>sure </em><em>about</em><em> </em><em>it </em><em>since </em><em>in </em><em>the</em><em> </em><em>case </em><em>it </em><em>is </em><em>not </em><em>g</em><em>iven </em><em>that </em><em>how </em><em>much </em><em>miles </em><em>he </em><em>walk </em><em>in </em><em>total </em><em>so.</em>
<em>I </em><em>just </em><em>added </em><em>the </em><em>no.</em><em> </em><em>of </em><em>miles </em><em>he </em><em>walk </em><em>in </em><em>part </em><em>A </em><em>and </em><em>B </em><em>so </em><em>I </em><em>got </em><em>x </em><em>=</em><em> </em><em>5</em><em>1</em><em>.</em><em>5</em>
