Answer:
no
Step-by-step explanation:
its is not a solution, however if the equal sign actually looks like
![\leqslant](https://tex.z-dn.net/?f=%20%5Cleqslant%20)
then it would be yes
Draw a plane, showing the three (non-linear) points that define it.

The answer is 105 because 180-75=105
Answer:
8 + 4i
Step-by-step explanation:
according to the bi form, the solution to the expression √4+ √−4+√36 + √−4 would be 8 + 4i
Answer: (d)
Step-by-step explanation:
Given
Annual profit is given by
![P=10x^2-280x+1600](https://tex.z-dn.net/?f=P%3D10x%5E2-280x%2B1600)
When it is factored then,
![\Rightarrow 10x^2-280x+1600=0\\\Rightarrow 10\left( x^2-28x+160\right)=0\\\Rightarrow x^2-20x-8x+160=0\\\Rightarrow x(x-20)-8(x-20)=0\\\Rightarrow (x-8)(x-20)=0\\\Rightarrow x=8,20](https://tex.z-dn.net/?f=%5CRightarrow%2010x%5E2-280x%2B1600%3D0%5C%5C%5CRightarrow%2010%5Cleft%28%20x%5E2-28x%2B160%5Cright%29%3D0%5C%5C%5CRightarrow%20x%5E2-20x-8x%2B160%3D0%5C%5C%5CRightarrow%20x%28x-20%29-8%28x-20%29%3D0%5C%5C%5CRightarrow%20%28x-8%29%28x-20%29%3D0%5C%5C%5CRightarrow%20x%3D8%2C20)
On factorization, we get that annual profit is zero at a whole prize of $8 and $20.
