Write a linear function f with the values f(−1)=5 and f(3)=4.

Answers

Answer 1

Answer:

1 Expert Answer When they say f(0) = -5 they mean the point (0, -5) is on the line. When they say f(3) = 4 they mean the point (3, 4) is on the line. In y = mx + b form, we would have f(x) = 3x - 5.

Step-by-step explanation:

Answer 2

The function is to be determined from the given points.

The linear function is [tex]f(x)=-\dfrac{1}{4}x+\dfrac{19}{4}[/tex]

The given values are

[tex]f(-1)=5[/tex]

[tex]f(3)=4[/tex]

The ordered pairs are [tex](-1,5),(3,4)[/tex]

The equation of the line is

[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)\\\Rightarrow y-5=\dfrac{4-5}{3-(-1)}(x-(-1))\\\Rightarrow y-5=-\dfrac{1}{4}(x+1)\\\Rightarrow y-5=-\dfrac{1}{4}x-\dfrac{1}{4}\\\Rightarrow y=-\dfrac{1}{4}x-\dfrac{1}{4}+5\\\Rightarrow y=-\dfrac{1}{4}x+\dfrac{19}{4}[/tex]

Tawnee is designing a playground in the shape of a rectangle. If Tawnee increases the length and width of the playground by a scale factor of 2
what will be the resulting effect on the perimeter of the new playground?
The perimeter of the new playground will be half the perimeter of the original playground
The perimeter of the new playground will be 1/4 the perimeter of the original playground
The perimeter of the new playground will be twice the perimeter of the original playground
O The perimeter of the new playground will be four times the perimeter of the original playground

Answers

Answer:

We conclude that If Tawnee increases the length and width of the playground by a scale factor of 2, the perimeter of the new playground will be twice the perimeter of the original playground.

Step-by-step explanation:

We know that the perimeter of a rectangle = 2(l+w)

i.e.

P = 2(l+w)

Here

'l' is the length'w' is the width

Given that the length and width of the playground by a scale factor of 2

A scale factor of 2 means we need to multiply both length and width by 2.

i.e

P = 2× 2(l+w)

P' = 2 (2(l+w))

    = 2P      ∵ P = 2(l+w)

Therefore, we conclude that If Tawnee increases the length and width of the playground by a scale factor of 2, the perimeter of the new playground will be twice the perimeter of the original playground.

A cable television provider charges $75 for installation and $39.96 per month for a basic entertainment package. a satellite television provider offers free installation and charges $13.32 per month for service for each television. your neighbor subscribes to the cable provider the same month you subscribe to the satellite provider. after how many months is your neighbor's total cost the same as your total cost when you own three televisions?

Answers

The total cost will never be same for me and my neighbor.

Let us assume the number of months when cost will be equal for both me and my neighbors be x.

So, my cost of cable = Cost per month per television × number of televisions × number of months

My cost of cable = 13.32 × 3 × x

My cost of cable = 39.96x

Cost of cable for my neighbor = One time installation cost + Cost per month × number of months

(Assuming neighbor has 1 television as the number is not specified)

Cost of cable for my neighbor = 75 + 39.96 × x

Cost of cable for my neighbor = 75 + 39.96x

We need to equal the cost for both, so relating the equation -

39.96x = 75 + 39.96x

It is clear that equation can not be solved for the value of x. Hence, it can be concluded that cost of cable for me and my neighbor will never be equal. Also, my cost of cable will always be less.

(2): x+y= 3

(1)×3: - 2x+3y= - 6 ... (3)

Answers

Answer:

The distance between the boats after 1 minute is 17 ft

Step-by-step explanation:

Here, we want to calculate the distance between the boats after 1 minute

The distance covered by the first boat after 1 minute is 2 feet while for the second it is 1 foot

So for the first boat, it has 8 ft ahead, for the second boat, it has 9 ft ahead

So the distance between the two after 1 minute will be 9 ft + 8 ft = 17 ft

Titus works at a hotel. Part of his job is to keep the complimentary pitcher of water at least half full and always with ice. When he starts his shift, the water level shows 8 gallons, or 128 cups of water. As the shift progresses, he records the level of the water every 10 minutes. After 2 hours, he uses a regression calculator to compute an equation for the decrease in water. His equation is W –0.414t + 129.549, where t is the number of minutes and W is the level of water. According to the equation, after about how many minutes would the water level be less than or equal to 64 cups?

150 minutes
160 minutes
170 minutes
180 minutes

Answers

Answer: b. 160

Step-by-step explanation: just took the test

There are 160 minutes would the water level be less than or equal to 64 cups.

What is Inequality?

A relation by which we can compare two or more mathematical expression is called an inequality.

Here, The equation we're given is,

W = -0.414t + 129.549,

which an be written as,

-0.414t + 129.549 = W.

Now, We are asked to find the amount of time it would take for the water level to be less than or equal to 64 cups.  

Plugging this information in, we have:

-0.414t + 129.549 ≤ 64

To solve this, we first cancel 129.549 by subtracting from both sides:

-0.414t + 129.549 - 129.549 ≤ 64 - 129.549

-0.414t ≤ -65.549

Now divide both sides by -0.414:

-0.414t/-0.414 ≤ -65.549/-0.414

t ≥ 158.33

(When we multiply or divide both sides of an inequality by a negative number, we must flip the inequality symbol.)

t ≥ 160 minutes

Thus, There are 160 minutes would the water level be less than or equal to 64 cups.

Step-by-step explanation:

I graphed the equation in my graphing calculator and it came up with a kind of v shaped graph. If you look at the question and see that we first house to school, that would probably mean from the left side of the graph to the center (0,4). Then we go from school to friend's house, so it must be from the center to the right side of the graph. Therefore, the school must be the y intercept (0,4) as that is the center of the graph.

When you convert a decimal to a percentage, if it is set up with "0." in front, then just swap the number behind the decimal and put it in front of the zero and add a percentage sign. When converting a percentage to a decimal, you reverse the process. Then the others are simple multiplication and division!

Snow is falling steadily in Syracuse, New York. After 2 hours, 4 inches of snow has fallen. How many inches of snow fall in 6 1/2 hours?

Answers

Answer:

12.2 inches of snow ... sorry if its incorrect

Step-by-step explanation:

Answer:

13 inches of snow would fall in 6 1/2 hours.

Step-by-step explanation:

We can apply a point system:

In zero hours, zero inches of snow would fall. (0,0)

In two hours, four inches of snow would fall. (2,4)

Since the rate of the snowfall is linear (steady), we could create a linear equation.

y = 2x, where x is the time in hours and y is the snowfall in inches.

We need to figure out what y would equal if x = 6.5 (6 1/2 hours).

Plugging in x = 6.5 in our equation:

y = 2 * 6.5

  = 13

number of apples, 2, and the number of bananas, y, that Hailey bought
Determine three ways to Have a total of 14 apples and bananas:
Cost of apples: $0.00
Cost of bananas: 50.00

Answers

Answer:

a = 4

b = 10

Step-by-step explanation:

Price of an apple $1.25

Price of a banana $0.5 0

The two equations:

10 = 1.25a + 0.5b

a + b = 14

solve for one variable

b = 14 - a

10 = 1.25a + 0.5(14-a)

10 = 1.25a+ 7 - 0.5a

10 = 0.75a + 7

0.75a = 3

a = 4

Then solve for the second

b = 14 - 4

There are 52 cards in a standard deck: 13 hearts, 13 clubs, 13 diamonds , and 13 spades. Timothy draws four cards at random from the deck, one of each suit. If he draws again , without replacing the four he drew, what is the probability that the next card is a heart

Answers

Answer:

[tex]\dfrac{1}{4}[/tex]

Step-by-step explanation:

Total number of cards in a standard deck = 52

Number of hearts in the deck = 13

Number of clubs in the deck = 13

Number of diamonds in the deck = 13

Number of spades in the deck = 13

Four cards are drawn at random by Timothy.

These four cards are drawn from each one of the suits.

And the cards are not replaced.

Therefore, now cards remaining in each suit:

Remaining number of hearts in the deck = 12

Remaining number of clubs in the deck = 12

Remaining number of diamonds in the deck = 12

Remaining number of spades in the deck = 12

Formula for probability of an event E can be observed as:

[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text {Total number of cases}}[/tex]

Here, number of favorable cases are 12 (i.e. number of hearts)

Total number of cases = 12 [tex]\times[/tex] 4 = 48

Therefore, the required probability is:
