Step-by-step explanation:
Answer:
-2
Step-by-step explanation:
Rearrange for w
-12/6 = -2
Have a great day :)
So 18 is most likely gonna be D 19.5 then question 19 looks a bit bigger so I would go with A 22.5 or it’s gonna be C 19.5 so flip a coin on that one and now for question 20 it’s gonna be 11.3
Answer:
When a graph has 2 x-intercepts, it will have positive discriminant & when a graph has NO x-intercepts, it will have negative discriminant.
Step-by-step explanation:
In a quadratic equation, the discriminant is the value of . This is "under the square root sign" when solving using quadratic formula.
Thus, there can be 3 possibilities:
1. Discriminant is 0 ( 2 equal real roots - meaning 1 touching point at the x-axis in the graph)
2. Discriminant can be positive ( 2 distinct real roots - meaning 2 cutting point in the x axis)
3. Discriminant can be negative ( 2 complex roots - meaning NO cutting point in x-axis)
Thus, when a graph has 2 x-intercepts, it will have positive discriminant & when a graph has NO x-intercepts, it will have negative discriminant.
Answer:
Yes
Step-by-step explanation:
I think it would be every domain has 1 range
Hope It helps Have a Good day
