Yes because when you have y = -3x²-7x -6 it is just the same as f(x) = -3x² -7x - 6

Answer:

  (13,-23)

Step-by-step explanation:

Comparing the image coordinates to the transformation rule, you see that ...

  (x -4, y +15) = (9, -8)

Adding (4, -15) to these coordinates, we get ...

  (x -4, y +15) +(4, -15) = (9, -8) +(4, -15)

  (x-4+4, y+15-15) = (9+4, -8-15)

  (x, y) = (13, -23) . . . . coordinates of D

9. Determine whether (-3,2) is a solution of<br> Y = 2x +8<br> Y= -X+1
miss Akunina [59]
2 = 2(-3) + 8
2 = -6 + 8
2 = 2

true.

2 = 3 + 1
2 = 4

false.

this is not a solution because both equations have to be true.

Solve 8(1/4×+3/4)-3=17
stepladder [879]
8(1/4x + 3/4) -3 =17

First distribute which results in (8/4x + 24/4)-3 =17.
Now just simply simplify it into (2x+6)-3 =17
Then you combine like term : 2x+3 =17

Subtract 3 on both sides : 2x=14

Finally divide 2 on both sides to isolate x: x=7
