For this case we have to:
Given the quadratic equation of the form:

The roots are given by:

If we have: 
We can rewrite it in the following way:

Where:

Where we have:



By definition: 




Thus, the roots are given by imaginary numbers:

Answer:

Answer:
-3
Step-by-step explanation:
First step to this is to replace the variables with their coordinated values. Remember to use parentheses.
4(2)-2(2+4)+1=?
We can start to simplify.
4(2)-2(6)+1
Then---
8-12+1
-4+1
Final Answer (-3)
Answer:
Equation: y =
x
21/2 cups of water
Step-by-step explanation:
Plug in 7 as y and 4 as x
7 = 4k
Find k
k = 7/4
Then plug k into th equation
y = 7/4 x
For the second part of the question:
Plug in x which is 6 into the bolded equation.
y = (7/4)(6) = 42/4 = 21/2 (simplified form)
21/2 cups of water
