Step-by-step explanation:

Both coefficients are divisors of the constant, so the intercepts are integer values. This makes it easy to graph the line using the x- and y-intercepts.

x-intercept

Set y=0 and you get ...

  x = 6

y-intercept

Set x=0 and you have ...

  3y = 6

  y = 2 . . . . divide by 3

46. An olympic athlete has just completed a four mile run. His average time was 6 minutes per mile. If he ran the first and last mile in 5 minutes, and the other 2 were the same time as each other, what was the average time for the 2 miles in the middle

Answers

Answer:

7 minutes

Step-by-step explanation:

average time = 6 minutes per mile

sum = average * count = 6 minutes / mile * 4 miles = 24 minutes

first + last mile = 5 + 5 = 10 minutes

first + second + third + last mile = sum = 24 minutes

second + third = sum - first - last = 24 - 5 - 5 = 24 - 10 = 14 minutes

average of 2 miles in the middle = sum / count = 14 minutes / 2 = 7 minutes

y 1 2 3 4

Answers

Answer:

x 2-2 3-3

y 5 5  7 7

Step-by-step explanation:

Each domain, or x value, can only be matched with one y value, so given this, the third one is the answer since every domain is only matched with one range, or in other words, there are no repeating domains in on the x row of the table.

The table that represents a function is

x  2  -2  4   -4

y  8  8   12   12

Option D is the correct answer.

What is a function?

A function has an input and an output.

A function can be one-to-one or onto one.

It simply indicated the relationships between the input and the output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

A function can have many to one but a function can not have one to many.

So,

From the table,

x  2  -2  4   -4

y  8  8   12   12

This is a many-to-one function.

All the other tables are one-to-many functions.

Thus,

The table that represents a function is

x  2  -2  4   -4

y  8  8   12   12

Katie works as a waitress and records her monthly tips in the table shown below. If Katie decided not to work the month of November, how would her five month average compare to her six month average for monthly tips? June July August Septemper October November $133. 45 $235. 31 $239. 45 $258. 87 $298. 45 $115. 67 a. Her monthly average would have decreased by $19. 57. B. Her monthly average would have increased by $19. 57. C. Her monthly average would have increased by $2. 7. D. Her monthly average would have decreased by $2. 7. Please select the best answer from the choices provided A B C D.

Answers

Her monthly average would have decreased by $19.57 and it can be determined by using taking the average value of every month.

Given that,

Katie works as a waitress and records her monthly tips in the table shown below.

June, July, August, September, October, November

$133.45, $235.31, $239.45, $258.87, $298.45, $115.67

If Katie decided not to work the month of November,

We have to determine,

How would her five-month average compare to her six-month average for monthly tips?

According to the question,

Katie works as a waitress and records her monthly tips in the table below.

June, July, August, September, October, November

$133.45, $235.31, $239.45, $258.87, $298.45, $115.67

To find out how not working in November would affect the average of Katie's tips.

The average of her working June until October only.

[tex]\rm Average = \dfrac{133.45 + 235.31 +239.45 + 258.87 + 298.45}{5}\\\\Average =\dfrac{ 1165.53 }{ 5}\\\\Average = 233.10[/tex]

Then, The average is with the month of November is,

[tex]\rm Average = \dfrac{133.45 + 235.31 +239.45 + 258.87 + 298.45 + 115.67}{6}\\\\Average =\dfrac{ 1281.2 }{ 6}\\\\Average = 213.53[/tex]

 

Therefore,

On comparing the average of her five-month average to her six-month average for monthly tips is,

[tex]233.10 - 213.53 = 19.57[/tex]

The average will decrease because 213.53 is less than 233.10.

Therefore, Her average will decrease by $19.57.

Hence, Her monthly average would have decreased by $19.57.

Explanation:

"There are, however, three words in geometry that are not formally defined. These words are point, line and plane, and are referred to as the 'three undefined terms of geometry'"

If point, line, and plane are all undefined terms in Euclidean geometry, then that only leaves one answer left, c. bisector.

What is the equation of the line that passes through the point (-4,-3)(−4,−3) and has a slope of \frac{3}{4}

Answers

Answer:

y = 3/4x

Step-by-step explanation:

Given:

x1 = -4

y1 = -3

slope (m) = 3/4

Solution:

y - y1 = m ( x - x1 )

y - (-3) = 3/4 ( x - (-4) )

y + 3 = 3/4 ( x + 4 )

y + 3 = 3/4x + 3

y = 3/4x + 3 - 3

y = 3/4x

Answer:

75 seconds

Step-by-step explanation:

The graph intersects the x axis at 75 seconds.  That means y = 0, and y is the amount remaining (in ml).

After 75 seconds the amount of slushy left in the cup becomes zero the answer is 75 seconds.

What is a line graph?

A line graph is a type of graph where the data points are connected by segments of straight lines.

We have a line graph shown in the picture.

Sean is drinking a slushy as fast as he can. The amount of slushy left in the cup (in milliliters) as a function of time (in seconds) is graphed.

As we can see the amount of slushy left in the cup is decreasing as the time increases.

At time = 75 seconds

The amount of slushy left in the cup = 0

Thus, after 75 seconds the amount of slushy left in the cup becomes zero the answer is 75 seconds.
