Need help with question 11 and 12
qaws [65]

Answer:

  11.  your choices are correct

  12.  132°

Step-by-step explanation:

11. The given equations can be (re)written to slope-intercept form. Only those lines with a slope of 2 will be parallel to the given line.

  A: y = 2x -8 . . . . . slope = 2, an answer

  B: y = -2x +1 . . . . . slope = -2, not an answer

  C: y = -2x +7 . . . . .slope = -2, not an answer

  D: y = 2x +2 . . . . . slope = 2, an answer

  E: y = -2x -9 . . . . . slope = -2, not an answer

__

12. The marked angles are supplementary, so ...

  (3x -6)° +(x +2)° = 180°

  4x -4 = 180 . . . . . . . . . . . divide by °, collect terms

  x -1 = 45 . . . . . . . divide by 4

  x = 46 . . . . . . . . . add 1

Now, we can find the angle of interest.

∠PQR = (3x -6)° = (3·46 -6)°

∠PQR = 132°

Tyler was shoving an equation and his last line of work read -12=12. What does this mean
wolverine [178]

Answer:

Step-by-step explanation:

-12 = 12 ....this is incorrect...meaning no solutions

**

if it ended in :

x = a number, or y = a number...means there is 1 solution

if it ended in :

-12 = 12....incorrect answer, means there is no solutions

if it ended in :

2 = 2 or -4 = -4....correct answer, but not variable...means infinite solutions
