Answer:
-----> vertex form
-----> standard form
Step-by-step explanation:
we know that
The equation of a vertical parabola in vertex form is equal to
where
(h,k) is the vertex of the parabola
In this problem we have
substitute the values and solve for a
the equation in vertex form is equal to
Find the equation of the parabola in standard form
we know that
the equation of the parabola in standard form is equal to
we have
convert to standard form
The number is n. 12 is what is being diminished (made smaller), so something is subtracted. 6 times a number is 6n
12 - 6n, so a
From the graphs you can see that the graph of the line
lies under the graph of the line
. Then all solutions of unequality
are solutions of unequality
, but not all solutions of unequality
are solutions of unequality
.
For example, if x=1, y=-2
.
Answer: Correct choice is B.
Answer:
<h3>c = 20</h3>
Step-by-step explanation:
Use the Pythagorean theeorem:
a,b - leg lengths
c - hypotenuse length
We have a = 12 and b = 16. Substitute:
