here,
2x-6y= -12
2(x-3y)= -12
x-3y = -6...........eq1
x+2y=14............eq2
we can subtract the above two given equations
we get,
___________
so,
y=4
now to find the value of x we have to substitute the value of y in any of the above two equations, I choose eq2
we get,
<h3>so,</h3><h3> x=6,y=4</h3>
The answers are A C and E because all functions are linear equations and it is positive and would go up on a graph and goes up at a constant rate of 350. Hope this helps

Answer:
D) 560 ways
Step-by-step explanation:
Use the combinations formula: nCr = n! / (r! * (n-r)!)
16 choose 3 = 16! / (3! * 13!)
take out 13! in the numerator and denominator:
(16 * 15 * 14) / 6 = 560
