The answer is C. A way to find out is to add a few numbers from that group being specified. If you add 2 or even 100 to 3, the answer will be odd. If you add 12 to 3, you will get 15 which is a composite number. If you were to add 2 to 3, you will get 5 which is an odd number.
I belive it would be y=-5/1x+6?
But im only like 90% sure so dont take my word for it but i hope that right?
Answer:
D)
Step-by-step explanation:
f(x) = x^2 -14x -72
0=x^2 - 14x-72
0=x^2 - 18x+4x-72
0=x(x-18)+4(x-18)
0=(x-18)(x+4)
x-18=0 or x+4=0
x1=18 or x2=-4
asis of symmetry: x=(x1+x2)/2
x=(18+(-4))/2
x=14/2
x=7
