Answer:

Option 1 - y=-5x+12                              

Step-by-step explanation:

Given : A given line has the equation 10x+2y=-2

To find : What is the equation, in slope-intercept form, of the line that is parallel to the given line and passes through the point (0, 12)?

Solution :  

The slope intercept form is y=mx+c

where, m is the slope and c is the y-intercept.

Writing given equation in slope intercept form,

Equation 10x+2y=-2

Take x to another side,

2y=-10x-2

Divide both side by 2,

y=-5x-1

The slope intercept form of the equation is y=-5x-1

Where, m=-5 is the slope and c=-1 is the y-intercept.

When two lines are parallel their slopes are equal i.e. m_1=m_2

Let the equation be y=mx+c

As lines are parallel then m=-5

We have given lines passes through point (0,12).

Substitute in equation,

12=-5(0)+c

c=12

Substitute back in equation,

y=-5x+12

Therefore, The required equation is y=-5x+12

So, Option 1 is correct.

What are the 3 angle measures in the triangle shown below
7nadin3 [17]

9514 1404 393

Answer:

  B.  39°, 106°, 43°

Step-by-step explanation:

The sum of angle measures in a triangle is 180°. Then the sum of angle expressions will be 180.

  (3x +1) +(11x -4) +(5x -7) = 180

  19x -10 = 180 . . . . . collect terms

  19x = 190 . . . . . . . . add 10

  x = 10 . . . . . . . . . . . divide by 19

__

Then the three angle measures are ...

  • 3·10 +1 = 31
  • 11·10 -4 = 106
  • 5·10 -7 = 43

The appropriate choice is ...

  B.  31°, 106°, 43°
