Answer:
y=-5/8x-11/4
Step-by-step explanation:
y-y1=m(x-x1)
y-6=-5/8(x-(-14))
y-6=-5/8(x+14)
y=-5/8x-70/8+6
y=-5/8x-11/4
Step-by-step explanation:
true
and the top and bottom are just circles
<span>f(x) = 2x + 3
</span><span>g(x) = x²-7
</span>(f+g)(x) = f(x) + g(x) = 2x + 3 + x² - 7 = x² + 2x - 4
(f+g)(x) = x² + 2x - 4
Answer:
2-4 = -2
Step-by-step explanation:
It starts at 0, goes up to 2, then goes down 4.
Answer:
After solving we get ![\mathbf{i^3=-i}](https://tex.z-dn.net/?f=%5Cmathbf%7Bi%5E3%3D-i%7D)
Option D is correct.
Step-by-step explanation:
We are given:
If
we need to find the value of ![i^3](https://tex.z-dn.net/?f=i%5E3)
Solving:
![i=\sqrt{-1}](https://tex.z-dn.net/?f=i%3D%5Csqrt%7B-1%7D)
Taking cube on both sides
![i^3=(\sqrt{-1})^3\\](https://tex.z-dn.net/?f=i%5E3%3D%28%5Csqrt%7B-1%7D%29%5E3%5C%5C)
We can write
Using this for solving:
![i^3=(\sqrt{-1})^2.(\sqrt{-1})\\We \ know \ (\sqrt{-1})^2 =- 1 \ and \ \sqrt{-1}=1 \\i^3=-1(i)\\i^3=-i](https://tex.z-dn.net/?f=i%5E3%3D%28%5Csqrt%7B-1%7D%29%5E2.%28%5Csqrt%7B-1%7D%29%5C%5CWe%20%5C%20know%20%5C%20%20%20%28%5Csqrt%7B-1%7D%29%5E2%20%3D-%201%20%5C%20and%20%5C%20%5Csqrt%7B-1%7D%3D1%20%5C%5Ci%5E3%3D-1%28i%29%5C%5Ci%5E3%3D-i)
So, after solving we get ![\mathbf{i^3=-i}](https://tex.z-dn.net/?f=%5Cmathbf%7Bi%5E3%3D-i%7D)
Option D is correct.
