Answer:

x = 9

Step-by-step explanation:

Solving for x the equation

First with add 6 in each term in the equation in order to solve for x

6+3x+(-6) = 21+6

3x = 27

Then we divide both term for 3

3x/3=27/3

resulting

x = 27/3

Reducing

x = 9

Arisa [49]

Answer: 7

Step-by-step explanation:

(4+5)-2

You can either remove brackets and just do a little addition and subtraction.

4+5-2

9-2\\7

So the answer is 7.

Or just finish things inside the brackets first.

(4+5)-2\\9-2\\7

So the answer is 7.

What is the equation of a line with a slope of -2 that passes through the point (-2,12)?
slavikrds [6]

Answer:

y=-2x + 8 which is the required equation

Which is option C

Step-by-step explanation:

Given:

Slope = m = -2

Given points are ( -2,12)

Which is

x = -2 and y =12

TO find:

Equation of line passing through these points = ?

Solution:

The point slope form of a line is

y = mx + c

Here we don't know the value of c

To find it

Putting y = 12 , x= -2 and y = -2 in the given equation

y = mx + c

Putting values it becomes

12 = (-2)*(-2) + c

12 = 4 + c

Subtracting 4 from both sides

12-4 = 4 -4 + c

8 = c

Now we have

m = -2 and c= 8

So equation of a line is given by

y = mx + c

Putting value of m and c

y = -2*x + 8

y=-2x + 8 which is the required equation
