Answer:

46.5 miles

Step-by-step explanation:

Average speed × Time in hours = Distance

Average speed = 15.5 Miles per hour

Time = 180 minutes

We convert to hours

60 minutes = 1 hour

180 minutes = x

Cross Multiply

60x = 180

x = 180/60

x = 3 hours

Distance = 15.5 miles per hour × 3 hours

Distance = 46.5 miles

The distance Rico will ride his bicycle is 46.5 miles

Each answer choice below represents a relation by a set of ordered pairs. In which of the answer choices is the relation a funct
alexdok [17]

Answer:

A - Not Function

B - Function

C - Function

D - Not Function

E - Function

Step-by-step explanation:

For a relation to be a function, each value of input should have exactly one output. Which means that for one value of x, there should only one value of y. If the relation has repetition of x in its ordered pairs, it means that for one value of x, there are two or more values of y, hence the relation is not a function

(Consult the diagram below)

<h3>A - {(6,12),(3,1),(−1,13),(6,4)} </h3>

As x = 6 is being repeat, it means that x=6 has two values of y that are 12 and 4. IT IS NOT A FUNCTION.

<h3>B - {(−1,−2),(−4,−4),(0,−5),(7,−5)} </h3>

No repetition of x, IT IS A FUNCTION.

<h3 /><h3>C - {(−5,1),(4,10),(5,10),(6,7)} </h3>

No repetition of x, IT IS A FUNCTION.

<h3 /><h3>D - {(−1,4),(1,6),(−1,−2),(0,7)} </h3>

As x = -1 is being repeat, it means that x=-1 has two values of y that are 4 and -2. IT IS NOT A FUNCTION.

<h3>E - {(−2,8),(2,1),(−4,8),(7,9)}</h3>

No repetition of x, IT IS A FUNCTION.

Assume that y varies inversely with x. if y=7 when x=-2, find y when x=7
melisa1 [442]

Answer:

y=-2

Step-by-step explanation:

The formula for inverse variation is

xy =k

if y=7 when x=-2, we can substitute these numbers in to find k

(-2)(7) =k

-14 =k

The equation becomes

xy = -14

Let x =7

7y = -14

Divide each side by 7

7y/7 = -14/7

y = -2

A) Your primary concerns are the points B and E, so y> .5x+4 and y>or= x-4B) choose one or both points, and enter them into the equations. If the statements are true, then the equations work
