3 {x}(x - y) - 6 ({x}^{2}  - xy) \\  = 3 {x}^{2}  - 3xy - 6 {x}^{2}  + 6xy \\ =  3xy - 3 {x}^{2}

=3x(y-x)

Answer:

-3x ( x - y )

Step-by-step explanation:

3x ( x - y ) - 6 ( x² - x y )

<em>Solve the brackets.</em>

3x² - 3 x y - 6x² + 6 x y

<em>Combine like terms.</em>

3x² - 6x² - 3 x y + 6 x y

-3x² + 3 x y

Factorize the answer.

<u>-3x ( x - y )</u>

Which of the following equations best represents the graph of a function f(m)?
Inessa [10]

Answer: y = f(m)


Justification:


By definition, the graph of a function in the cartesian coordinate plane is the plot of the curve that join all the points that satisfy the equation of the function.


In the cartesian coordinate plane, each point is represented by a pair of coordinates (y, x). y is the value of the function f(x), and x is any input value of the function.


In this case, the function is given as f(m), which means that the input value is represented by m.


Hence, the graph is the plot of y = f(m).


The choice of the letter used for the variable is completely arbitrary and does not change either the math or the graph. It could have been said that the function is f(x) in which case the graph would be y = f(x). Nothing changes but the name that you use.

Which graph could potentially have a correlation coeffiecient (r value) of 0.95?
Masteriza [31]

Answer:

C,

Step-by-step explanation:

A and D is incorrect because they are negative correlation

and B is incorrect because a correction of 0.95 means all values are close to each other, but B values are scattered much more that C values

so answer C

Pls answer! Dylan spots an airplane on radar that is currently approaching in a straight line, and
anastassius [24]

Answer:

13510 ft

Step-by-step explanation:

I have attached a triangle diagram to depict this situation.

From the diagram, we see that distance between A and B is denoted by x.

Now, from trigonometric ratios in this type of triangle, let's first find y.

6400/y = tan 36

y = 6400/tan 36

y = 8808.84 ft

Now, we can find x from;

6400/(8808.84 + x) = tan 16

6400/tan 16 = 8808.84 + x

22319.452 = 8808.84 + x

x = 22319.452 - 8808.84

x ≈ 13510 ft

If y = kx, what is the value of k if y = 20 and x = 0.4? A) 5 B) 8 C) 9.6 D) 50
Margaret [11]
Answer: D, 50
y = kx          <span>y = 20 and x = 0.4
</span>
What you will do: You will plug in your y and your x.
Your equation should look like: 20=k(0.4)
Next: What you will do is divide each side of your equal sign by 0.4 so you will get your k alone.
You would get: k=50

HOPE THIS HELPS! ^_^
