Answer:

Step-by-step explanation:
We want to write the equation for a quadratic function in vertex form with vertex at (-1, 6) that passes through the point (-3, 4).
Vertex form is given by:

Where (<em>h, k</em>) is the vertex and <em>a</em> is the leading coefficient.
Since our vertex is at (-1, 6), <em>h</em> = -1 and <em>k</em> = 6. Substitute:

Simplify:

Next, since the quadratic passes through the point (-3, 4), f(x) = 4 when <em>x</em> = -3. Substitute:

Solve for <em>a</em>. Simplify:

Hence:

Therefore, our function in vertex form is:

Answer:
x = 3
Step-by-step explanation:

Answer:
Opposite sides are corresponding (AB = DC).
Opposite angles are corresponding (D = B).
Consecutive angles are supplementary (A + D = 180°).
If one angle is right, then all angles are right.
The diagonals of a parallelogram hemisect each other.
Step-by-step explanation:
I count five 'k's there, so that part of the expression is
k⁵ .
Two 'n's form the rest of it, so that part is n² .
The parts are multiplied, so the simplest form of the expression is
k⁵ n² .
