Calculate the distance between the points M=(-1, -2) and C=(-9, 2) in the coordinate plane.
Ivanshal [37]

Answer:

nearest hundredth 8.944

Step-by-step explanation:

d = √((x2-x1)2 + (y2-y1)2)

Step by step procedure:

Find the difference between coordinates:

(x2-x1) = (-9 - -1) = -8

(y2-y1) = (2 - -2) = 4

Square the results and sum them up:

(-8)2 + (4)2 = 64 + 16 = 80

Now Find the square root and that's your result:

Exact solution: √80 = 4√5

Approximate solution: 8.944

<h2>Hello!</h2>

The answers are:

3. Addition property of equality

4. 6x-7+7=12+7 - Simplification

7. x=\frac{19}{6}

<h2>Why?</h2>

To solve the problem, we need to start with the result of the second step:

6x-7=12

So,

For the step 3:

Then, for the 3rd step, we have to apply the addition property of equality.

The addition property of equality states that if we add a term to one side of the equality, we need to add it to the other side of the equality, in order to not alterate the equality.

Then, applying the property, we have:

6x-7=12

Adding 7 to both sides, we have:

6x-7+7=12+7

For the step 4:

Now, for the 4th step, we have to simplify the expression:

6x-7+7=12+7

Then, simplifying, we have:

6x=19

For the step 7:

Simplificating, we divide each side of the equality by 6:

\frac{6x}{6}=\frac{19}{6} \\\\x=\frac{19}{6}

Have a nice day!
