Using the Factor Theorem to find the equation of the parabola, we have that:
<h3>What is the Factor Theorem?</h3>
The Factor Theorem states that a polynomial function with roots 
is given by:
In which a is the leading coefficient.
In this problem, we have a horizontal parabola, defined as follows:
.
The roots are 
, hence:
f(y) = a(y + 1)(y + 7)
f(y) = a(y² + 8y + 7).
The x-intercept is of x = -3, hence f(0) = -3, so:
Then the equation is:
Then the sum of the coefficients is:

Answer:
You would get 8 cupcakes
Step-by-step explanation:
Since we're splitting C (cupcakes) with P (people) and we know that c = 88 and p = 11 we have to do the equation c / p or 88 / 11 which equals 8.
Answer:
QRS congruent to XYZ,
Look for congruent sides by the corresponding letters, example,
QR is congruent to XY
QS is congruent to XZ, and RS is congruent to YZ.
Same idea with angles,
angles QRS and XYZ are congruent,
angles RSQ and YZX are congruent, etc.
Step-by-step explanation:
Hope this helps:)
Answer:
D
Step-by-step explanation:
Since the shape won't change, it won't deform, nothing will happen to the interior angle.
This figure is symmetric and not deformed, so the measure of the interior angle won't change no matter how many times you rotate it.
So the interior angle would still be 135º.
Correct answer D
