Since x represents the year, year 15 will be 15 years.
Plug in "15" as your "x"
y = -2(15)^2 + 36(15) + 6
15^2 = 225 (Exponents come before multiplication)
y = -2(225) + 36(15) + 6
y = -450 + 540 + 6
y = 90 + 6
y = 96
<em>The answer is B</em>
Answer:

Step-by-step explanation:
center of the hyperbola is (0,0) = (h, k)
c = the distance form the center to either focal point = 100

The differences from the receiver to the transmitters = 2a
2a = 180 miles
a = 180/2=90 miles




The standard form is



Yes, because only equal groups can be multiplied
The difference between
i) <span>14k+2(3k+5)-5=10 and
ii) </span><span>14k+6k+10-5=10
is the equality </span>2(3k+5)=6k+10
The property used here, can be described for any numbers a, b and c as:

This is called the DISTRIBUTIVE PROPERTY
Answer: DISTRIBUTIVE PROPERTY
