Answer:

x = 18

Step-by-step explanation:

By the rule of Consecutive Interior Angles which define what these angles are, they both will add up to 180. As such we can put the sum of these two angles set equal to 180, and solve algebraically

(8x - 20) + (3x + 2) = 180

  8x - 20 + 3x + 2 = 180

                 11x - 18 = 180

                <u>      + 18    +18</u>

                         11x = 198                                                                                                                        

                            x = 198/11

                            x = 18

Write an equation of a line passing through the point (4,-9) and parallel to the line 3x-6y=30
sesenic [268]

The equation of a line in the slope intercept form is expressed as

y = mx + c

Where

m represents slope

c represents y intercept

The equation of the given line is expressed as

3x - 6y = 30

Rearranging it so that it will look like the slope intercept form, it becomes

6y = 3x - 30

Dividing both sides by 6, it becomes

6y/6 = 3x/6 - 30/6

y = x/2 - 5

Looking at the equation, slope, m = 1/2

If two lines are parallel, it means that they have equal slope. This means that the slope of the line parallel to the given line is 1/2

To determine the y intercept, c of the line passing through the point (4, - 9), we would substitute

x = 4, y = - 9 and m = 1/2 into the slope intercept equation. It becomes

- 9 = 1/2 * 4 + c

- 9 = 2 + c

c = - 9 - 2

c = - 11

By substtuting m = 1/2 and c = - 11 into the slope intercept equation, the equation of the line would be

y = x/2 - 11

PLEASE HELP!!! Solve for y.
ivolga24 [154]
- 2.1 = y/6 + 17.1
- 2.1 - 17.1 = y/6
- 19.2 = y/6
19.2*6 = y
-115.2 = y

So y = - 115.2.

Hope this helps ! This "/" is a fraction.
