2x+9<0
This is asking for numbers below 0
x>-12
This is asking for numbers above - 12

So the numbers which would fit in both of these rules would be:
-11, -10, -9, -8, -7, -6, -5

Any numbers above or below these wouldn't fit into any of the inequalities

On a coordinate plane, parallelogram H I J K is shown. Point H is at (negative 2, 2), point I is at (4, 3), point J is at (4, ne

Answer: HIJK is a parallelogram because the midpoint of both diagonals is <u>(1,0)</u> , which means the diagonals bisect each other.

Step-by-step explanation:

Given: The coordinates of parallelogram H I J K as

H is at (- 2, 2), point I is at (4, 3), point J is at (4, - 2), and point K is at (- 2, - 3).

Diagonals : HJ and IK [join opposite vertices]

Mid point of HJ = $(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2})$

$=(\dfrac{-2+4}{2},\dfrac{2+(-2)}{2})=(1,0)$

i.e. Mid point of HJ = (1,0)

Mid point of IK = $(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2})$

$=(\dfrac{4+(-2)}{2},\dfrac{3+(-3)}{2})=(1,0)$

i.e. Mid point of IK = (1,0) =Mid point of HJ

<em>When mid points of both diagonals are equal then that means the diagonals bisect each other.</em>

<em />

Thus, HIJK is a parallelogram because the midpoint of both diagonals is <u>(1,0)</u> , which means the diagonals bisect each other.

A quality-control center finds that 2 out of 250 toy trains are defective. How many trains would they expect to be defective in

kolbaska11 [484]

It would be C.80 because if you divide 10,000 by 250 then multiply the answer which is 40 by 2 the answer would be 80

Solve this equation. 25) v - 6(4v + 6) = -82

grin007 [14]

Answer:

$v = 2$

Step-by-step explanation:

Hi there! I'm glad I was able to help you solve this equation!

Let's start by simplifying both sides of the equation. It's easier to solve it this way!

$v - 6 (4v + 6) = -82$

Distribute:

$v + (-6) (4v) + (-6) (6) = -82$

$v + -24v + -36 = -82$

Combine 'like' terms:

$(v -24v) + (-36) = -82$

$-23v - 36 = -82$

Next, you'll want to add 36 to both sides of the equation.

$-23v-36 + 36 = -82 + 36$

$-23v = -46$

Finally, divide both sides by $-23$ .

$\frac{-23v}{-23} = \frac{-46}{-23}$

$v = 2$

I hope this helped you! Leave a comment below if you have any further questions! :)
