Answer:
where is the rest of the question?
Step-by-step explanation:
1, Might not be precise
2, Can be hard to plot the graphs
3, If there are many solutions that will be really hard to plot sometimes.
This is just from the top of my head.
Let's solve and find out.
4(2n - 4) + 3 = 8n - 19
8n - 16 + 3 = 8n - 19
8n - 13 = 8n - 19
-13 = -19
-13 and -19 are not equal, so the equation has no solutions.
Answer:
A. 0
Answer:
50%
Step-by-step explanation:
As there are only two sides of the coin it will be 50% each.
Step-by-step explanation:
For quadratic equation ax^2 + bx + c = 0 to have two distinct real roots,
b^2 - 4ac must be positive.
b^2 - 4ac > 0
(k - 3)^2 - 4(3 - 2k) > 0
k^2 - 6k + 9 - 12 + 8k > 0
k^2 + 2k - 3 > 0
