Answer:
Step-by-step explanation:
<u>To make the given piecewise function continuous we need:</u>
- ax² - b = 6 and 5ax + b = 6 at x = 1
<u>It gives us the system:</u>
- a(1²) - b = 6 ⇒ a - b = 6
- 5a(1) + b = 6 ⇒ 5a + b = 6
<u>Sum of the two:</u>
- a - b + 5a + b = 6 + 6
- 6a = 12
- a = 2
<u>Then b is:</u>
Answer:
8.2
Step-by-step explanation:
4(4)-7.8
Answer:
1662.768 --) rounded 1662.8
Since there's a common denominator, you can go straight into subtracting,
so for the top, x^2 + 8x - x^2 -2x + 6 will simplify to -6x -6 which with the bottom can be reduced (dividing everything by 3) to 2x - 2/x^2 + x
