Hello there!
This is a conceptual question about quadratic functions.
Remember that a solution of ANY function is where it intersects the x-axis, so if the quadratic function intersects the x-axis TWO times, this means that there are TWO real solutions.
Here's a list of things to remember that will help you out for quadratic functions...
•if a quadratic function intersects the x-axis twice, it has two real solutions.
•if a quadratic function intersects the x-axis once, it has one real solution and one imaginary solution.
•if a quadratic function intersects the x-axis zero times, it has zero deal solutions and two imaginary solutions.
Please NOTE: If you want to know how many solutions a polynomial function has, look at it's highest exponent. If it is 2, then it has 2 solutions whether they be real or imaginary. If it is 3, then it has 3 solutions.
Also, if one of the factors are the same for a polynomial function, the way it hits the x-axis changes! This is just some extra information to help you in the long run!
I hope this helps!
Best wishes :)
Answer: 0.32
Step-by-step explanation:
If every 10 minutes 3 buses leave then over a course of 60 minutes (1 hour ) 18 buses would leave
Answer:
-2
Step-by-step explanation:
Coefficient is usually the number in front of the variable so, in this case it would be -2.
The answer is 20. The way I do it is divide 12 by 6 then multiply it by 10 (it works as long as the denominator is ten).
