Answer:

The coefficient of the xy term in the expression is -4

Step-by-step explanation:

In an algebric expression, the coefficient is the number attached to a variable x,y,z.

For example in algebric equation 4x + 3y = 12

The coefficient of x is 4 and the coefficient of y is 3.

So in the given term 2x + 3y - 4xy - 10,

The coefficient of the xy term is -4

For this case we have the following expression:

2x + 3y-4xy-10

By definition, a coefficient is the term that accompanies one or more variables.

For example:

3x + 5

The coefficient of the linear term is 3.

So, in the given expression we have to:

-4 is the term that accompanies the variables xy.

Answer:

-4

Aloiza [94]

Answer:

2/7

Step to step explanation:

This question is in other words, asking you to simplify the fraction.

Find the GCF and divide both the denominator and numeratior by the GCF.

The GCF of 24/84 is 12.

24/12 = 2

84/12 = 7.

How old is the expanded notation method work
Akimi4 [234]
Well, 
For example 

2.34 * 10^6 will be....
2,340,000
It is because if you have the positive powers, you move your decimal to the right. In this case the power is 6 so you move your decimal to the right 6 times. 
Here's another example

1.23 X 10^-2 
The answer will be 0.0123 because you move your decimal two the left two times. The power is negative 2 so you move it to the left.

Final tips: If you have positive power, move it to the right and if you have negative power, move it to the left.

The quadratic function h(t) = -16.1? + 150 models a ball's height, in feet, over time, in seconds,
Sliva [168]
<h2>Hello!</h2>

The answer is: The first graphic representation.

<h2>Why?</h2>

We are given a quadratic equation, meaning that it could be two possible solutions for the exercise, however, we are talking about time, so we have to consider only the obtained positive values.

Let's make the equation equal to 0 in order to find the values of "t"

h(t) = -16.1t^2 + 150

0=-16.1t^2+150

16.1t^2=150

t^2=\frac{150}{16.1} =9.32

t=+-\sqrt{9.32} =+-3.05

t1=3.05

t2=-305

So, discarding the negative value, we can use the possitive value to find the correct graphic representation.

To find the correct graphic representation we must take into consideration the following:

- We must remember that the sign of the coefficient of the quadratic term (t^2) will define if the parabola opens downward or upward.

From the given quadratic (or parabola) equation we have:

a=-1

b=0

c=150

So, since the coefficient of the quadratic term is negative, the parabola opens downward.

- Since we are looking for a graphic that represents the change in height over time, we need to look for a graphic that shows only positive values for the x-axis (time)

- We are looking for a parabola which y-axis intercept is equal to 150.

Therefore, the graphic representation of the quadratic function that models a ball's height over time is the first graphic representation.

Have a nice day!
