Answer:
![z_1\times z_2=-14+27i](https://tex.z-dn.net/?f=z_1%5Ctimes%20z_2%3D-14%2B27i)
Step-by-step explanation:
We are given that two complex numbers
![z_1=3-4i](https://tex.z-dn.net/?f=z_1%3D3-4i)
![z_2=-6+i](https://tex.z-dn.net/?f=z_2%3D-6%2Bi)
We have to find the product of two complex numbers
![z_1\times z_2=(3-4i)(-6+i)](https://tex.z-dn.net/?f=z_1%5Ctimes%20z_2%3D%283-4i%29%28-6%2Bi%29)
![z_1\times z_2=3(-6+i)-4i(-6+i)](https://tex.z-dn.net/?f=z_1%5Ctimes%20z_2%3D3%28-6%2Bi%29-4i%28-6%2Bi%29)
![z_1\times z_2=-18+3i+24i-4i^2](https://tex.z-dn.net/?f=z_1%5Ctimes%20z_2%3D-18%2B3i%2B24i-4i%5E2)

![z_1\times z_2=-14+27i](https://tex.z-dn.net/?f=z_1%5Ctimes%20z_2%3D-14%2B27i)
Answer:
Step-by-step explanation:
3(x - 2) = -27
3x - 6 = -27
3x = -21
x = -7
Answer:
F(x) = -3(x + 2)² - 2
Step-by-step explanation:
In the picture attached, the graph is shown.
F(x) has the form a(x - h)² + k, where (h, k) is the vertex of the parabola. We can see in the graph that the vertex is located at (-2, -2), then F(x) = a(x + 2)² - 2. If a > 0 the parabola opens upward, if a < 0 the parabola opens downward. We can see in the graph that the parabola opens downward, then the correct answer is F(x) = -3(x + 2)² - 2
Answer:
-6 + 57
Step-by-step explanation:
Substitute the value of the variable into the equation and simplify.
