Find the constant of variation k for inverse variation. Then write an equation for the inverse variation. y= 5 when x = 7.5 k = 37.5;y = 37.5/x k = 15;xy = 1.5 k = 2.5;y = 2.5/x k = 37.5;y=37.5x

Answers

Answer 1
Answer: direct variation has this formula: y = kx
inverse variation has this formula: y = k/x

y = 5 ; x = 7.5 ; k = 37.5

y = k/x ⇒ 5 = 37.5 / 7.5 ⇒ y = 37.5/x
Answer 2
Answer:

Answer:k=37.5 ; xy=37.5

You average 55 miles per hour while driving to a relative's house. On the return trip, you average 50 miles per hour because of bad weather. The total driving time is 5 hours and 15 minutes. How long does each trip take?

Answers

We conclude that the frist trip takes 2.75 hours and the second one 2.5 hours.

How long does each trip take?

Remember the relation:

Distance = Speed*Time.

Here the total distance of the trip is 55mi + 50mi = 105mi

And the total time is 5 hours and 15 minutes, remember that:

60 min = 1 hour

Then; 15 min = 0.25 hours.

So the total time is 5.25 hours, with that we conclude that the average speed is:

S = 105mi/5.25 h = 20 mi/h

The first trip is 55 miles long, then the time in which it is travelled is:

T = (55 mi)/(20 mi/h) = 2.75 hours

The second trip is 50 miles long, then:

T' = (50mi)/(20 mi/h) = 2.5 hours.

We conclude that the frist trip takes 2.75 hours and the second one 2.5 hours.

Is the following relation a function?two ovals, one labeled x and the other labeled y. The negative 2 in the x oval is pointing to the 5 in the y oval, the 0 in x is pointing to 1 and 3 in y, 5 in x pointing to 8 in y, and 7 in x pointing to 5 in y

Yes

No

Answers

The answer is No.
Because the 0 in x oval is pointing to BOTH 1 and 3 in y oval.
And that must not happen in order to relation be a function.
The following conditions must be satisfied for relation to be a function:
1. condition: EVERY element in first oval has to be connected to some element in second oval.
2. condition: Elements in first oval MUST NOT have more than one connection with elements in second oval.

The answer is B (no)
