The discriminant can be determined from the number of roots of the graph.
If Disc> 0, the function has two distinct roots
If Disc = 0, the function has a repeated root
If Disc < 0, the function has no real root.
Since the given graph has no real root, i.e. it does not cross x-axis at any point, so we can say that the discriminant of the given function is negative.
So the answer to this question is option C
Answer:
5
Step-by-step explanation:
To solve this problem, we need to set up a system of equations. Let x represent the larger number and y represent the smaller number.
x + y = 17
x - y = 7
We can solve this system by adding them together. The y cancels out because y + (-y) = 0. After that, we solve for x
2x = 24
x = 12 (Divide both sides by 2)
Now that we know the value of x, we can substitute it into one of our original equations to solve for y.
12 + y = 17
y = 5 (Subtract 12 from both sides)
So, the smaller number is 5.
Answer:
1/4+m=2/3
It's too short. Write at least 20 characters to explain it well.
Answer:
You’re right!
Step-by-step explanation:
It IS 3, heres why:
it follows the same rule each time:
2X=Y
1 times 2 is 2
6 times 2 is 12
11 times 2 is 22
16 times 2 is 36
thats proportionate! :D
i hope this helps!
