So you have your equations: 2x-4y=0 and -x+2y=1

Depending on the variable you want to take out, depends on how your equation will be set up, but, I'm going to take out X.

With the first equation you subtract 2x from 0 which leaves you with -4y=-2

Divide the sum and you get a positive 2x.

Plug 2 into X on the following equation, it should look like this. -2+2y=1. This time you're trying to find Y so, add 2 to 1 and you get 2y=3. Divide this and it should give you a decimal.

Apply the Pythagorean Theorem to find the distance between points A and B.

Answer:

Properties of a right tangle can be created in a Coordinate Plane

Distance between two points A and B are shown as below

Step-by-step explanation:

Find distance between two point using Pythagorean Theorem.

Properties of right triangles and creating right triangle as a coordinate Plane.

Suppose two point are drawn in triangle containing value of (-2 , 4 ) and (-2, -2)

then

In (-2 , 4 ) and (-2,-2)

taking y-values that is 4 and -2

find difference between them such as

4-(-2) = 6

Distance is (-2,4) is 6 unit from (-2,-2)

We can also find unit length of A and B

Side A: (-1, 2) and (3,2)

3-(-2) = 5

side A is 5 unit in length

Side B : (-2,2) and (-2,-1)

2 - (-1) = 3

Side B is 3 unit in length

Answer:

x=−1 or x=−9

Step-by-step explanation:

x2+11x+10=x+1

Step 1: Subtract x+1 from both sides.

x2+11x+10−(x+1)=x+1−(x+1)

x2+10x+9=0

Step 2: Factor left side of equation.

(x+1)(x+9)=0

Step 3: Set factors equal to 0.

x+1=0 or x+9=0

x=−1 or x=−9

Shelly has a roll of fabric and decides to make some scarves for her friend the roll contains 6 2/3 yards of fabric she needs 5/

ivann1987 [24]

Answer:

Step-by-step explanation:

Total length of the fabric is $6\dfrac{2}{3}=\dfrac{20}{3}\ \text{yards}$

We need to find the number of scarves can she make if she needs 5/6 of a yard for each scarf.

Let she needs x scarves. So, ATQ

$x\times \dfrac{5}{6}=\dfrac{20}{3}\\\\x=\dfrac{20}{3}\cdot\dfrac{6}{5}\\\\x=8$

Hence, she can make 8 scarves.
