Wen is incorrect.
The reason being is that the function does not continue in both directions from the origin. Since we cannot have a negative value of people, we cannot use all values of x as inputs in the equation. Therefore, it is not continuous.
The answer is d + 0.25(d - 22) = 10.75
d - the amount of dollar coins
q - the amount of quarters
It is given: d + q = 22
The quarter is $0.25, therefore:
d + 0.25q = 10.75
Now, we have the system of equations:
d + q = 22
d + 0.25q = 10.75
According to the first equation:
d + q = 22 <span>⇒ q = 22 - d</span>
We will replace q in the second equation:
d + 0.25q = 10.75 ⇒ d + 0.25(22 - d) = 10.75
Answer:
Step-by-step explanation:
<u>Factor x³ + 2x:</u>
1. <u>The common factor is x, then</u>:
- 2 + k = 0 ⇒ k = -2 (all the rest are divisible by x)
2. Factor x² + 2 is not linear therefore we discard it.
