We have that
y=-3x²<span>+5x+11
we know that
the equation of the parabola in standard form can be expressed in one of the following two ways
y=ax</span>²+bx+c
<span>the parabola opens up if a is positive and opens down if a is negative
and
x=ay</span>²+by+c
the parabola opens right if a is positive and opens left if a is negative
<span>
in this problem
the equation is of the form
</span>y=ax²+bx+c<span>
a=-3
so
the parabola opens down
using a graph tool
see the attached figure
the vertex of a parabola is a maximum
the answer is</span>
the parabola opens down
Answer:
Both of them are not functions
Step-by-step explanation:
In the first one you can see that the numbers repeat (You can't have that in a function)
And the second one is a circle, which can never be a function.
48/3= 16 (cups)
16+16= 32 (twice as many plates)
So it would be 16
Answer:
I cant see it
Step-by-step explanation:
I cant see it
4x - 26 = 3x + 4
-3x -3x
x - 26 = 4
+26 +26
x = 30
Since the 2 angles are opposite of each other you would set them equal to each other.
