The answer is C. x<span> ≤ </span>3
Answer:
364.
Step-by-step explanation:
14C3 = 14! / 11! 3! which simplifies to:
14*13*12 /3*2*1
= 14*13* 2
= 364.
Solution,
y = -x-4......(i)
3x + y =- 16.......(ii)
Now,
Substituting the value of y in equation (ii)
or, 3x + (-x-4)= -16
or,3x - x - 4 = -16
or, 2x= -16 +4
or, x = -12/2
: x = -6
Then,
Substituting the value of x in (i) equation;
or,y= -(-6) - 4
or,y= 6 - 4
: y =2
