Answer:
a=1, b=1/3, c=1/27
Step-by-step explanation:
The table is given below:

(a)As the exponents decrease, the next term is gotten by a division of the previous term by 3.

(b)

a=1, b=1/3, c=1/27
<span>A) 5x - 14y + 6z
You add the numbers together that have the same letter.
EX: 7x - 2x = 5x</span>
Answer:
y = -1/4(x +4)² +4
Step-by-step explanation:
The equation of a parabola with focus (a, b) and directrix y=d can be written using the form ...
y = 1/(2(b-d))(x -a)² +(b+d)/2
<h3>Application</h3>
We are given (a, b) = (-4, 3) and d=5. Using these values in the above form gives the equation ...
y = 1/(2(3-5))(x -(-4))² +(3+5)/2
y = -1/4(x +4)² +4
