Which of the following equations describes the line shown below? Check all that apply (-2,6) and (4,3)

1 answer:

7 0

A and F are true. because A is y=2x+7, and F is y=2x+7.
We know that the equation y=2x+7 has a point 0,7 and with the slope being 2, rise over run would make another point 1,9. And because these are linear equations if the equation y=2x+7 goes through 1,9 then it will go though -2,3 as well.

QveST [7]

Answer:

$F(x) = |x|$

And we need to apply some transformations. The first part is hift 8 units left. And we need to do this:

$F(x) = |x+8|$

Then we need to apply the second transformation Shift 3 units down. and we can do this:

$F(x) = |x+8|-3$

Step-by-step explanation:

For this case we have the following function given:

$F(x) = |x|$

And we need to apply some transformations. The first part is hift 8 units left. And we need to do this:

$F(x) = |x+8|$

Then we need to apply the second transformation Shift 3 units down. and we can do this:

$F(x) = |x+8|-3$

Two chicken coops are to be built adjacent to one another from 168 ft of fencing. What dimensions should be used to maximize the

Cerrena [4.2K]

Answer:

21 ft by 28 ft

Step-by-step explanation:

To maximize the area, see the attached.

Perimeter will be 4l+3w which is equal to the fencing perimeter, given as 168

4l+3w=168

Making l the subject then

4l=168-3w

l=42-¾w

Area of individual land will be lw and substituting l with l=42-¾w

Then

A=lw=(42-¾w)w=42w-¾w²

A=42w-¾w²

Getting the first derivative of the above with respect to w rhen

42-w6/4=0

w6/4=42

w=42*4/6=28

Since

l=42-¾w=42-¾(28)=21

Therefore, maximum dimensions are 21 for l and 28 for w

My couch potato friend enjoys sitting in front of the TV and grabbing handfuls of 6 chocolates at random from his snack jar. Unb

Nikolay [14]

Answer:

There are 8008 possible outcomes are there the first time he grabs 6 chocolates

Step-by-step explanation:

The order in which the chocolates are chosen is not important. So the combinations formula is used to solve this question.

Combinations formula:

$C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

How many possible outcomes are there the first time he grabs 6 chocolates?

6 chocolates from a set of 16. So

$C_{16,6} = \frac{16!}{6!(16 - 6)!} = 8008$

There are 8008 possible outcomes are there the first time he grabs 6 chocolates

Time Limit!

DENIUS [597]

The correct answer is B.3,072. The method is quite simple all you need to do is add the previous number to itself in order to get the next term e.g 3+3=6.............24+24= 48 until the eleventh term.

Hope this helps ya
