What is the equation of the line that is

Mathematics
1 answer:
Fantom [35]3 years ago

Answer:

y = m_{AB}(X-2)-1

Step-by-step explanation:

When two lines are parallel means that their slopes are equal. Therefore the line AB will have same slope to a parallel second line, m_{AB} = m_{2}.

To obtain the slope from the line AB, we need two points, so the general equation will be:

m_{AB} = \frac{y_{B} -y_{A}  }{x_{B}-x_{A}  }

The typical equation of a line is written as y = mx + b

The second line will pass through point (2, -1), so we can substitute:

y2 = mX2 + b

-1 = -1=m_{AB} (2)+b(2) + b

then the interception is b=-m_{AB} -1

Now to obtain a general equation for the second parallel line will be:

y =  m_{AB} X + b

y =  m_{AB} X - m_{AB}(2)-1

Finally we get:

y =  m_{AB} (x-2)-1

How would you convert a mass in centigrams to a mass in milligrams??
const2013 [10]
First let's start with the relationship between grams and centigrams and grams and milligrams.

1 gram = 100 centigrams
1 gram = 1000 milligrams

Because these two equations are equal, we can rewrite our equation as 100 centigrams = 1000 milligrams.

Now we divide by 100 to simplify our equation to 1 centigram = 10 milligrams.

With this simplified equation we see that we multiply the number of centigrams by 10 to find the equal number of milligrams.

Answer:

-2

Step-by-step explanation:

First you should write out the entire word equation into one you may recongnize:

7x - 12 = -3x - 32

After this, solve for x:

7x + 3x = 12 - 32

<u>10x</u> = <u>-20</u>

10      10

x = -2

the number is -2
