Step-by-step explanation:
The first equation is x=0.
the second equation has no solution.
Answer:
12
Step-by-step explanation:
When n teams play each other once, the total number of games is n(n-1)/2. Since each team played every other one 3 times, the relationship between number of teams (n) and number of games is ...
3(n(n-1)/2) = 198
n(n-1) = 132 = 12·11 . . . . . . multiply by 2/3 and factor
n = 12 . . . . . . n = -11 is also an extraneous solution to this quadratic equation
12 teams participated in this championship.
Answer:
12 + -6i
a=12
b=-6
Step-by-step explanation:
( -4 + 3i ) ( -3 - 2i )
-4 * -3 = 12
3i * -2i= -6i
12 + -6i
Alright so, let’s break this down.
To find the first coordinate you need to solve the first equation
To do that you can do
6+9=15
So that mean 3x has to be equal to 15
You divide 15 by 3
The answer to that is the solution to the first equation, or the first coordinate.
For the second one, you know x has to be negative because the solution is negative
2x is going to have to equal -20
-20/2 gets you the solution
Remember that it will be negative
You now have both of the coordinates
You take coordinate A and technically add coordinate B to it
You do that because B is negative and A is positive
Then you have the answer to c
