8 0

Answer:

12x^2 -21x -6

Step-by-step explanation:

(3x-6)(4x+1)

FOIL

first 3x*4x= 12x^2

outer 3x*1 = 3x

inner -6*4x = -24x

last  -6*1 = -6

Add them together

12x^2 +3x -24x -6

Combine like terms

12x^2 -21x -6

Write a paragraph of a real life situation you can use the graph as and explain how u would fit it onto the graph.
ivann1987 [24]

We can use this graph in the situation of an animal population of an animal species that grows exponentially until the death of Jesus, and from that point began to decrease exponentially.

It fit in the graph of the following way:

The y-axis represents the number of animals, and the x axis represents the passing of time, 0 becomes the moment in which the calendar stops being taken as before Christ and starts to be taken as after Christ.

What is the length of Line segment B C, rounded to the nearest tenth? 13. 0 units 28. 8 units 31. 2 units 33. 8 units.
Len [333]

The length of the line segment BC is 31.2 units.

<h2>Given that</h2>

Triangle ABC is shown.

Angle ABC is a right angle.

An altitude is drawn from point B to point D on side AC to form a right angle.

The length of AD is 5 and the length of BD is 12.

<h3>We have to determine</h3>

What is the length of Line segment BC?

<h3>According to the question</h3>

The altitude of the triangle is given by;

\rm Altitude = \sqrt{xy}

Where x is DC and y is 5 units.

Then,

The length DC is.

\rm Altitude = \sqrt{xy}\\&#10;\\&#10;12 = \sqrt{(DC) \times 5}\\&#10;\\&#10;\sqrt{DC } = \dfrac{12}{\sqrt{5}}\\&#10;\\&#10;

Squaring on both sides

\rm DC = \dfrac{144}{5}\\&#10;\\&#10;DC = 28.8

Considering right triangle BDC, use the Pythagorean theorem to find BC:

\rm BC^2 = DC^2+BD^2\\\\  BC^2 = (28.8)^2+(12)^2\\&#10;&#10;\\&#10;BC = \sqrt{829.44+144}\\&#10;\\&#10;BC = \sqrt{973.44}\\&#10;\\&#10;\rm BC = 31.2 \ units

Hence, the length of the line segment BC is 31.2 units.

Which statement about the ordered pairs (3, −8)(3, −8) and (4, 4)(4, 4) is true for the equation 3x−y4=11
sleet_krkn [62]
The answer is D.) Neither ordered pair is a solution.

The reason being:

If we look at the ordered pair (3,-8) and plug it into the equation like so:

3(3)-(-8)4=11
9-32=11
-23=11
FALSE

Now let's look at the ordered pair (4,4):

3(4)-4(4)=11
12-16=11
-4=11
FALSE

We see that neither ordered pair works, so the answer is D.) neither is a solution.

Hope this helped :)
