Step-by-step explanation:
 
        
             
        
        
        
3x - 2y = 1
2x + 2y = 4
Add the second equation to the first
5x     = 5
2x + 2y = 4
Divide the first equation by 5
x        = 1
2x + 2y = 4
Subtract the first equation from the second
x        = 1
x + 2y = 3
Subtract the first equation from the second again
x        = 1
    2y = 2
Divide the second equation by 2
x        = 1
       y = 1
<h3>
So, the solution is  x = 1  and  y = 1  {or: (1, 1)} </h3>

brainly.com/question/9247314You obviously don't mind using "technology" (Brainly) to answer these questions. A graphing calculator can do quadratic regression on the sequence and tell you its formula.
If you want to do it by hand, you can write the equation
.. y = ax^2 +bx +c
and substitute three of the given points. Then solve the resulting three linear equations for a, b, and c.
.. 4 = a +b +c
.. 7 = 4a +2b +c
.. 12 = 9a +3b +c
Subtracting the first equation from the other two reduces this to
.. 3 = 3a +b
.. 8 = 8a +2b
The latter can be divided by 2, so reduces to 
.. 4 = 4a +b
Subtracting the first of the reduced equations from this, you have
.. 1 = a
so
.. 3 = 3*1 +b
.. 0 = b
and
.. 4 = a + b + c = 1 + 0 + c
.. 3 = c
And your equation is
.. y = x^2 +3 . . . . . . as shown previously
 
        
        
        
Answer:
A.)
Step-by-step explanation:
15 multiplied by 14 is the total number of women’s players.
14(m) is our unknown amount of men’s teams
Which has to be less than the amount of players who can register 476
