For
y=ax²+bx+c
the x value of the axis of symmetry is -b/(2a)
so test them
A., -b/(2a)=-(-8)/(2*-2)=8/-4=-2, yep
B. -b/(2a)=-2/(2*1/2)=-2/1=-2, yep
C. -b/(2a)=-(-16)/(2*4)=16/8=2, nope, need -2
D. -b/(2a)=-12/(2*3)=-12/6=-2, yep
answer is C
Answer:
If 9x is not =27, then x is not =3
Step-by-step explanation:
Going out on a limb here, please ignore if I'm missing it:
If 9x is not =27, then x is not =3
(I can't type the equal sign with a slash through it.)

Answer:
Step-by-step explanation:
Q) 5 × (4/9) = ?
→ (5 × 4)/9
→ 20/9
Ofcourse it is a linear function
why because every of x value of this function is 23 in result always
... so when we draw a chart it will be line on 23 coordinate ;)
