10v^3 -18v^2 +12v
This is because you have to change the sign of the second polynomial due to the negative sign. Then you can add.
Answer:
f(x) = x^2 -3
Step-by-step explanation:
A function is translated down 3 units by subtracting 3 from the function value. For the parent function f(x) = x^2, the translated function is ...
f(x) = x^2 -3

<em>Comment on vertex form</em>
The full "vertex form" has the values of the vertex coordinates in the equation explicitly. For vertex (h, k), the form is ...
f(x) = a(x -h)^2 +k
We have moved the vertex from (0, 0) to (0, -3). The vertical scale factor (a) remains 1. So, we could write the equation as ...
f(x) = 1(x -0)^2 -3 . . . . vertex form with unnecessary parts shown
Removing the identity elements doesn't change anything (though it requires a little practice to see them when they aren't there). So, with minor simplification, this becomes ...
f(x) = x^2 -3
The <em>correct answer</em> is:
D) Rotated perpendicular lines always remain perpendicular lines.
Explanation:
Perpendicular lines, by definition, meet at a 90° angle.
As long as both lines are rotated the same direction and the same angle, then the angle between the two lines will not change. They will continue to be perpendicular, no matter how many degrees or which direction they are rotated.
Answer:
32x-96
Step-by-step explanation:
8 · 4x = 32x
8 · 12 = 96
The answer to the equation. is 2
