Answer:

(- 1, - \frac{1}{2} )

Step-by-step explanation:

The centre is located at the midpoint of the diameter.

Using the midpoint formula , then

centre = \frac{-10+8}{2}, \frac{-5+4}{2} ) = ( \frac{-2}{2}, \frac{-1}{2} ) = (- 1, - \frac{1}{2} )

Factor completely<br><br> 20x^2 y - 4xy<br><br> Someone put steps for me when solving, thank you
zavuch27 [327]

20x^2y - 4xy

First, we look at what terms are common between each term.

There is a 4 present in the last term, and 4 is a factor of 20, so that is one factor.

Each term also includes at least one x, and one y, so x and y are also factors.

We can factor a 4, an x, and a y out of this.

<h3><u>4xy(5x - 1) is the fully factored form of this binomial. </u></h3>

Which is the graph of 2x + 3y &gt;-3?
Cerrena [4.2K]

Answer:

The third graph is correct for the inequality 2x + 3y > -3

Step-by-step explanation:

The slope of the graph is –2/3.

The y-intercept is –1

The area above the dashed be line is shaded.

To verify, choose a coordinate in the shaded area, substitute the values for x and y. Calculate and check.

For example: (1,1)

2(1) + 3(1) > –3

2 + 3 > –3

5 > –3 True.
