Answer:
1. 10x^2 -4
2. 2a^5 + 5b
Step-by-step explanation:
1. Simplify 4(x^2 -1) to 4x^2 -4
then add that to 6x^2
2. 4a^5 - 2a^5 = 2a^5 and
4b+b = 5b
Answer:
5.45 hours.
Step-by-step explanation:
The formula =
P = P0(10)t
In this circumstance, P0 = 275, P = 15,000 and t = ?
Applying the values into the formula:
P = P0(10)t
15,000 = 275 × (10) × t
15,000 = 2750t
t = 15,000/2750
t = 5.45 hours
The two coordinates' x variables are the same, while the y variables change. This means that it is reflected over the x axis. Reflecting over the y axis would cause a change in the x variable, as it would have to move sideways, so this can't be the case since the x variable stays as 4 even after the reflection.
