Answer:
Step-by-step explanation:
we know that
The quadratic equation in vertex form is equal to
where
a is the leading coefficient
(h,k) is the vertex of the quadratic equation
Remember that
In a quadratic equation the turning point is the same that the vertex
so
(h,k)=(-1,-16)
substitute
we have one zero at (-3,0)
substitute and solve for a
substitute
Convert to standard form
I think it’s C I hope it helps
Answer:
Option h: 16h
Step-by-step explanation:
To get the answer to the question divide 480 by 30 to get the rate which is 16. So the answer would be H
To simplest form of a fraction you find the lowest common factor, usually I use this trick: if both numbers are even I keep dividing by 2 to the numerator and denominator till I can't anymore
In this case:
6 divided by 2= 3
--- ---
8 divided by 2= 4
now I can't simplify an further because 3 isn't an even number, therefore its the simplest form
remember= my trick only works if both number are even, if not you'll have to find the lowest common factor and divide them by that
Think of it like this:
of = multiplication of the equation
is= equals
and whatever you are looking for is your variable
so....
.40 times X = 56
