Answer:
7
General Formulas and Concepts:
- Degree of Polynomial is determined by the highest power
Step-by-step explanation:
<u>Step 1: Define function</u>
P(x) = 7x⁷ + 2x⁵ + 7x + 7
<u>Step 2: Identify</u>
7x⁷ is the largest term.
- Has the highest power
- Therefore, highest degree
Answer:
D and E because they are bigger than 28. C is 28 but there isn't a greater OR EQUAL sign next to it
Answer:
Since Tracy is charged $29 for 250 free minutes so:
For x ≤ 250, f(x) = $29
tracy is charged an extra $0.35 per minute for calls over 250 minutes, so:
For x ≥ 250, f(x) = 29 + 0.35(x - 250)
We have the following expression:
By combining similar terms, we get
now, 2 times 3 is 6 and to add exponents, both the exponents and variables should be alike:
Similarly,
Therefore, the answer is
Answer: A: 6
B: 4
C: 2
