The answer is B) (2,-1).If you don’t believe me punch in the coordinates into a graphing calculator and then punch in (2,-1). It will give you a perfect parallelogram.

Answer:  The correct option is (B) (2, -1).

Step-by-step explanation:  Given that LMNO is a parallelogram where the co-ordinates of the vertices L,M and N are

L(-1,-1) ,  M(0,0)  and N(3,0).

We are to find the co-ordinates of the vertex O.

Let, (a, b) be the co-ordinates of the vertex O.

Since LMNO is parallelogram, so the opposite sides will be parallel.

That is, LM is parallel to NO. So, we have

\textup{slope of LM}=\textup{slope of NO}\\\\\Rightarrow \dfrac{0-(-1)}{0-(-1)}=\dfrac{b-0}{a-3}\\\\\\\Rightarrow \dfrac{1}{1}=\dfrac{b}{a-3}\\\\\Rightarrow b=a-3\\\\\Rightarrow a=b+3~~~~~~~~~~~~~~~~~~~~~~~~~~(i)

and MN is parallel to OL. So,

\textup{slope of MN}=\textup{slope of OL}\\\\\\\Rightarrow \dfrac{0-0}{3-0}=\dfrac{-1-b}{-1-a}\\\\\\\Rightarrow 0=\dfrac{b+1}{a+1}\\\\\\\Rightarrow b+1=0\\\\\Rightarrow b=-1.

Therefore, from equation (i), we get

a=-1+3=2.

Thus, the co-ordinates of vertex O are (2, -1).

Option (B) is correct.

Each unit on the grid stands for one miles determine two ways to calculate the distance from josie's house to annies
Novosadov [1.4K]
I encountered this problem before but it had an accompanying image and list of answer choices.

I'll attach the image and include the list of options. 

Each unit on the grid stands for one mile. Determine two ways to calculate the distance from Josie's house to Annie's house.
A) Distance Formula and Slope Formula
B) Midpoint Formula and Slope Formula
C) Distance Formula and Midpoint Formula
<span>D) Distance Formula and Pythagorean Theorem
</span>
My answer is: D.) Distance formula and Pythagorean Theorem.

When looking at the image, I can visualize a right triangle. I'll simply get the measure of the long and short legs and solve for the hypotenuse. 
Since the distance formula is derived from the Pythagorean theorem, it can be used to determine the distance from Josie's house to Annie's house.

Can someone pls help need it ASAP and can you pls explain in full detail how to do it
GenaCL600 [577]

Answer:

x= 1 , y=4

Step-by-step explanation:

x-y= -3 => Equation 1

x+5y= 21 => Equation 2

<u>Substitut</u><u>ion</u><u> </u><u>Method</u><u>:</u>

<u>Substitu</u><u>te</u><u> </u><u>Equation</u><u> </u><u>1</u>=>

x=y-3 <= Equation 3

Put x=y-3 in Equation 2:

x+5y=21

( y-3)+5y=21

y-3+5y=21

6y-3=21

6y=21+3

6y=24

y=24÷6

y=4

Put y=4 in Equation 1:

x-y= -3

x-4=-3

x=4-3

x=1

Hope this helps :)

What constant term is necessary to complete the perfect square trinomial pictured in the algebra tiles?
gayaneshka [121]
The algebra tiles show two equal factors. They are (x + 4).


Then, the perfect square is the product of the two equal factors, (x + 4) * (x +4).


That is (x + 4)^2.


Then develop that perfect square to find the constant term.


(x + 4)^2 = x^2 + 8x + 16.


That means that the constant term needed to complete the trinomial is 16.
