I will put this into fractions for you- I hope you meant that
Step-by-step explanation:
15x turns into 30/2x
-4y turns into -8/2x
And finally 18 turns into 36/2
So the whole equation looks like this-
30/2x-8/2x=36/2
P.S. I just multiplied everything by 2 and put 2 as the denominator
Answer:
Therefore, the exact value of Tan 60 degrees is √3. We can also derive the values of tan 0°, 30°, 45°, 90°, 180°, 270° and 360° in the same way
You can see the side conditions for the function. We read the x CANNOT be 4. See it?
We evaluate the bottom piece at x = 4. Let's do that.
f(x) = -2x
Let x be 4.
f(4) = -2(4)
f(4) = -8
What about the other piece?
Evaluate the top piece at x = 2.
Let's do that.
f(x) = 3x
Let x be 2.
f(2) = 3(2)
f(2) = 6
Answer: Choice D
Did you follow? It is a piecewise function. Solve it one piece at a time keeping each side condition in mind along the way.
Answer:
f(7) = 13.7
f(8) = 18.7
Recursive Function Is: f(1) = -16.3; (fn) = f(n - 1) + 5
Step-by-step explanation:
The recursive function of the arithmetic sequence is
f(1) = first term; f(n) = f(n-1) + d, where
- d is the common difference between each two consecutive terms
∵ f(5) = 3.7 and f(6) = 8.7
∵ d = f(6) - f(5)
∴ d = 8.7 - 3.7
∴ d = 5
∵ f(7) = f(6) + 5
∴ f(7) = 8.7 + 5
∴ f(7) = 13.7
∵ f(8) = f(7) + 5
∴ f(8) = 13.7 + 5
∴ f(8) = 18.7
→ To find f(1) subtract from each term the value of d
∵ f(5) = f(4) + d
∴ f(4) = f(5) - d
∴ f(4) = 3.7 - 5
∴ f(4) = -1.3
∵ f(3) = f(4) - 5
∴ f(3) = -1.3 - 5
∴ f(3) = -6.3
∵ f(2) = f(3) - 5
∴ f(2) = -6.3 - 5
∴ f(2) = -11.3
∵ f(1) = f(2) - 5
∴ f(1) = -11.3 - 5
∴ f(1) = -16.3
∴ Recursive Function Is: f(1) = -16.3; (fn) = f(n - 1) + 5
