Would the answer be +18??????????
8x-4y=24, 2x-y=6, y=2x-6
so, 4x-6(2x-6)=28
x=1
y=-4
Hope that answer can help you!
Answer:
Step-by-step explanation:
Given
Required
Determine the type of roots
Represent Discriminant with D; such that
D is calculated as thus
And it has the following sequence of results
When 
then the roots of the quadratic equation are real but not equal
When 
then the roots of the quadratic equation are real and equal
When 
then the roots of the quadratic equation are complex or imaginary
Given that ; This means that and base on the above analysis, we can conclude that the roots of the quadratic equation are complex or imaginary
Answer:
A proportional relationship is any relationship that stays constant. since both sides of the equation do not change, this is a proportional relationship
