Answer:
degree of the polynomial is highest power of x in P(x) .

So degree is 5.
18 - 7x = -20.5
Subtract 18 from each side:
-7x = -38.5
Divide both sides by -7:
x = -38.5 / -7
x = -5.5 = 5 1/2
The answer is D.
Answer: 2 4/5
Step-by-step explanation:
14/3 - 2 2/5
14/3 - 12/5
= 34/15
= 2 4/15
The answer to the question
Replace x with -4 so it would be:
f(-4)= 2(-4)=-8
-8 is your answer
