Well, if a minute is 60 seconds, and she typed 10 words in 15 seconds, we can easily calculate the words per minute. Since 15 * 4 = 60, we need to do the same with 10. Ten * 4 = 40, so she cannot enter the typing contest. I hope this helps you.

There are 60 seconds in a minute.  So first we take 60 and divide it by 15.  That gives us 4.  So there are 4 15 second increments where Pat types 10 words.  So if she types 10 words in 15 seconds, and there are only 4 15 second increments in a full minute, then she can't enter because she can only type 40 words per minute.

Find the image of the points after a reflection in the line x=-2​
meriva

Answer:

The Y value part of the point's coordinates will always stay the same, and then calculate the distance from the point's x value to the line -2 and then count the same amount in the opposite direction. For example, if the point was (-3,1), then the point is 1 left from the line, so you will go point one right from the line and get the answer (-1,1)

Mathew is watching a car race on TV. His favorite car covered 10 laps of 3.6 miles each in 18 minutes. What is average speed of
Karo-lina-s [1.5K]
In the given question, all the necessary information's are already provided. Using these information's it is easy to find the average speed of the car in miles per hour. It is given that the car covers 10 laps in 18 minutes and each lap is 3.6 miles in length.
Total distance covered by the car = (10 * 3.6) miles
                                                     = 36 miles
Now we have to convert the time from minutes to hours. So
18 minutes = 18/60 hours
                   = 3/10 hours
Now we can easily calculate the average speed of the favorite car of Mathew.
Average Speed = 36 * (10/3) miles/hour
                           = 120 miles/ hour

Write the formula of the function y whose graph is shown. A. Y equals 1 divided by x minus 4. B. Y equals 4 divided by the quant
aliina [53]

Answer:

Option D. Y equals 4 divided by x.

Step-by-step explanation:

The picture of the question in the attached figure

we know that

Looking a t the graph

For x=1, y=4

For x=4, y=1

For x=-1, y=-4

For x=-4, y=-1

therefore

The equation that satisfy  these values is

y=\frac{4}{x}

Help me with this math question please I'm giving away brainliests ​
alex41 [277]

Answer:

Step-by-step explanation:

Given function is,

f(x)=\frac{2x^2+6x}{-4x^2+8x}

       =\frac{2x(x+3)}{-4x(x-2)}

This function is not defined at "x(x - 2) = 0"

Therefore, for the values of x = 0 and 2, given function is not defined.

Vertical asymptote → x = 2 [Denominator = 0]

For Horizontal asymptote → [\frac{2x^2}{-4x^2} =-\frac{1}{2}]

Therefore, horizontal asymptote → y = -\frac{1}{2}

x-intercept,

For f(x) = 0,

Numerator of the function = 0

2x² + 6x = 0

2x(x + 3) = 0

x = -3

Therefore, x - intercept → (-3, 0)

For y-intercept,

x = 0

f(0) = 0

Therefore, graph has no y-intercept.

For holes on the graph,

Since, function is not defined at x = 0,

f(x) = \frac{(x+3)}{-2(x-2)}

f(0) = \frac{(0+3)}{-2(0-2)}

     = \frac{3}{4}

Therefore, hole on the graph → (0, \frac{3}{4})
