Answer:
3x³ - 12x + 4
Step-by-step explanation:
The opposite of a polynomial P is -P.
You find the opposite of P by multiplying it by -1.
P = -3x³ + 12x - 4
-P = (-1)( -3x³ + 12x - 4) Distribute -1 to each term
= (-1)(-3x³) + (-1)(12x) - (-1)(4) Multiply each coefficient by -1
= 3x³ + (-12)x - (-4)
= 3x³ - 12x + 4
Subtract 1 from both sides
3 - 1 = -2x
Simplify 3 -1 to 2
2 = -2x
Divide both sides by -2
-1 = x
Switch sides
<u>x = -1</u>
797,100 deaths x
---------------------------------- = -------------------------
350,000,000 people 100,000 people
or:
797,100 deaths x
--------------------------- = -----------------
3500 people 1 people
Result: 228 deaths per 100,000 people
