The value of the function f (x) is 15/2 when x = -5 and is -73/2 when x = 3. What is the equation of the function?

Answers

Answer 1

Answer:

y = -5.5x - 20

Step-by-step explanation:

There are many functions that cross those points.

Assuming you're looking at a straight line.

y = mx + b

15/2 = -5m + b  --> 7.5 = -5m + b

-73/2 = 3m + b  --> -36.5 = 3m + b

Subtract the first from the second.

-44 = 8m

m = -5.5

Plugging back into the first equation, we get b = -20

Answer 2

Answer:

f(x) = −11/2x − 20

A parent is using a garden hose to fill up a small inflatable pool for her young child. The pool has a capacity of 90 gallons. She turns the water off after 5 minutes, but leaves the hose in the pool for another 3 minutes before putting it away.

In this situation, the relationship between the gallons of water in the pool and the 8 minutes since the parent started filling the pool can be seen as a function.

In that function, which variable is independent? Which one is dependent?

Type your response in the space below.

Answers

Answer:

Independent variable = the time. Dependent variable = amount of water per minute

Step-by-step explanation;

The total amount of water depends on how long the hose is left on.

The relationship between the gallons of water in the pool and the 8 minutes since the parent started filling the pool can be seen as a function is ''the total amount of water depends on how long the hose is left on''.

Time is the independent variable.

The amount of water per minute is the dependent variable.

The pool has a capacity of 90 gallons.

She turns the water off after 5 minutes but leaves the hose in the pool for another 3 minutes before putting it away.

What is the independent variable?

Independent variables are the variables that the experimenter changes to test their dependent variable.

What is the dependent variable?

A change in the independent variable directly causes a change in the dependent variable.

1. The relationship between the gallons of water in the pool and the 8 minutes since the parent started filling the pool can be seen as a function is ''the total amount of water depends on how long the hose is left on''.

2. Time is the independent variable.

A gym charges $8.75 for each swimming class and a one-time registration fee of $12.50. A student paid a total of $56.25. How many swim classes did the student take?

Answers

Answer:

He took 5 swimming classes.

Step-by-step explanation:

The problem states that the student paid a total of $56.25 for the classes and also the one-time registration fee. To find the number of classes, we should first subtract the one-time registration fee from the total.

$56.25 - $12.50 = $43.75

Now that we know he spent a total of $43.75 on the classes without the registration fee, we can divide that number by the cost of one class ($8.75) to calculate the total number of classes he took.

43.75 / 8.75 = 5

Will give brainliest if correct.

A flat-screen television was marked down by 35 percent, which reduced its price by $115.65. What was the original cost of the television before it was marked down?
$214.78
$330.43
$404.78
$4,047.75

Answers

Answer:

B

Step-by-step explanation:

35% of this price is :

35/100 × x = 0.35x

The price reduces by 0.35x.

This equals to 115.65

Now :

0.35x = 115.65

100/35 × 115.65 = 330.43

Trudy bought a $20 prepaid long distance phone card. for every minute that she talks, $0.25 is deducted from her card. The function f(m)=20-0.25m represents the amount of money f(m) she has left after talking m minutes.FInd the zero and explain what it means in the context of the situation.

Answers

Answer:

Step-by-step explanation:

Given the function f(m)=20-0.25m to represent the amount of money f(m) she has left after talking m minutes, the zero of the equation can be gotten by setting f(m) to 0

f(m)=20-0.25m

0 =20-0.25m

-20 = -0.25m

m = -20/-0.25

m = 80

Hence Trudy will have talked for 80minutes if she has no money left

Answer: x = 160

Step-by-step explanation:

540 = 100+(x-25)+(x-15)+(1/2)x+(1/2)x

540= 100-40+3x = 60+3x

480 = 3x

x = 160

Answer:

0.5x + 0.5x + (x-25) + (x-15) + 100 = 540

x + x - 25 + x - 15 + 100 = 540

3x + 60 = 540

3x = 540 - 60

3x = 480

x = 480/3

x = 160
