In the coordinate plane, quadrilateral ABCD has vertices A(-2, 3), B(4,5), C(10, -1), and D(8, -9). Let E, F, G, and H

Aliun [14]

Answer:

G(3, 1), H(2, 3)

Step-by-step explanation:

When D is the midpoint of EG, it means ...

D = (E + G)/2

or

G = 2D -E = 2(3,4) -(3,7) = (2·3-3, 2·4-7) = (3, 1)

Likewise, H is ...

H = 2D -F = 2(3,4) -(4,5) = (2·3-4, 2·4-5) = (2, 3)

not my answer but i hope it helps you.

4x2 + y2 = 36 Obtener dominio

Veronika [31]

Answer:

[-3,3]

Step-by-step explanation:

Write the problem as a mathematical expression.

4x^2+y^2=36

Subtract 4x^2 from both sides of the equation.

y^2=36-4x^2

Take the square root of both sides of the equation to eliminate the exponent on the left side.

y= + and - $\sqrt{36-4x^2}$

The complete solution is the result of both the positive and negative portions of the solution.

y= $2\sqrt{(3+x)(3-x)$

$y= -2\sqrt{(3+x)(3-x)}$

Set the radicand in $\sqrt{(3+x)(3-x)} \geq 0$ greater than or equal to 0 to find where the expression is defined.

$(3+x)(3-x)\geq 0$

So your answer would be [-3,3]

Which statement best explains whether the table represents a linear or nonlinear function?

natali 33 [55]

The attached file is the points graphed.
So what is a linear function?
If it is a linear function, its graph will be a straight line.
It also must have either one or two variables. If there is another variable is, it must be a known variable or constant.

The points and the graph satisfy both of these things, so we know the answer is not B or D.

So, let's look at both answer choices.

A.It is a linear function because the input values are increasing.
C.It is a linear function because there is a constant rate of change in both the input and output.

Well, according to our criteria, the input values don't need to be increasing for it to be linear. But, we do know that there must be a constant rate of change in both the input and output.

So, the answer is C. It is a linear function because there is a constant rate of change in both the input and output.
