This is not an equation because it lacks an equal sign....so the only thing we can do here is combine like terms.
4 - 2x - 12 - 2x + 1 =
-4x - 7
Answer:

Step-by-step explanation:
Notice that they are asking you to write the equation of the parabola in vertex form, that is using the coordinates of the vertex
in the expression:

we can start by directly replacing the given vertex coordinates (-3, -3) in the expression, and then using the extra info on the point the parabola goes through in order to find the parameter
:

So, now we can write the full expression for the parabola:

Answer:
112
Step-by-step explanation:
Answer:
1.-204.5 2.-557
Step-by-step explanation:
Answer:
26
Step-by-step explanation:
Because DAC is a straight line we can equate that:
4x - 8 + 34 + 76 - x = 180
3x + 102 = 180
3x = 78
x = 26
