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:
the 3rd number line
Step-by-step explanation:
first of all, we know That the line starts from zero.
the inequation is n>0
the circle inside should be the hallow one because it's "greater" not greater than or equal to.
n>0 means that n is greater than 0.
in the number line, ( the 3rd one) n is going away from 0. it's going greater than 0.
that is why this is the correct answer.
I hope this clarified any confusion.
Answer:
290 cm
Step-by-step explanation:
There are 100 centimeters in a meter so 1.3m*100 is 130cm
130+160cm is 290cm.
Answer:
where is the functions
Step-by-step explanation:
The answer is not it is not because if you use the vertical line test it does not pass and if you plotted the coordinates then x would repeat multiple times
Hope this helps
Have a great day/night
