The rate of change in this situation is 3 to 1. Every hour you spend running you are able to advance three miles. 2 hours = 6 miles 3 hours = 9 miles 4 hours = Mindblown+ 12 miles.

Hope this Helps! :)

The answer you are looking for is B. If you use the FOIL method (first,outer,inner,last) of multiplication, you will find that (x+5) times (x-5) is actually x^2+25. Hope this helps! Comment if you have questions!!! :)

There is a line that includes the point (4, 1) and has a slope of 1/4. what is its equation in

Lelechka [254]

Answer:

y=1/4x

Step-by-step explanation:

y=mx+b

m=1/4

so, y=1/4x+b

Now, look at our line's equation so far: . b is what we want, the 1/4 is already set and x and y are just two "free variables" sitting there. We can plug anything we want in for x and y here, but we want the equation for the line that specfically passes through the the point (4,1).

So, why not plug in for x the number 4 and for y the number 1? This will allow us to solve for b for the particular line that passes through the point you gave!.

(4,1). y=mx+b or 1=1/4 × 4+b, or solving for b: b=1-(1/4)(4). b=0.

y=1/4x+0

Answer:

<em>The area of the rectangle is</em> $A=12b^6+6b^3-18b^2$

Step-by-step explanation:

<u>Area of a rectangle</u>

A rectangle of height H and width W has an area of:

$A=H*W$

The rectangle shown in the figure has a height of:

$H=3b^2$

And a width of

$W=4b^4+2b-6$

The area is

$A=(3b^2)(4b^4+2b-6)$

Operating:

$A=(3b^2)*4b^4+(3b^2)*2b-(3b^2)6$

$A=12b^6+6b^3-18b^2$

The area of the rectangle is $A=12b^6+6b^3-18b^2$

Please HELP ASAP!!! The dot plot show the number of hours teenagers spent on two different websites last week. Which statement i

Delvig [45]

Answer:

(F.) the mode of the data for website K is greater than the mode of the data from website L

Step-by-step explanation:

Mode simply means the parameter that occurs the most.

In website K, the one that occurs the most is 8 hours while in website L, the one that occurs the most is 2 hours.

This means that mode of website K is greater than that of website L.

Thus,statement F is correct

Range is the difference between the highest value and the lowest value..

For website K, Range = 14 - 1 = 13

For website L, Range = 13 - 1 = 12

Thus,range of both websites are not the same and as such statement G is wrong.

For a symmetrical distribution, the left and right hand sides of the centre value line of the distribution have to mirror each other.

In this case neither website K nor L have that. Thus, statement H is not correct.

Skewed to the left means that more o

dot points are found to the left of the graph.

For website L, more dot points are located to the left while for website K, it's not the case. Thus, statement J is not correct
