Work:
2x+5(6x+23)=-13
2x+30x+115=-13
32x=-128
x=-4
y=6(-4)+23
y=-24+23
y=-1
The answer is (-4,-1)
Hopefully this helps!
Answer:
i think its B
Step-by-step explanation:
a minimum requires the vertex to like be below the rest of the graph if that makes sense
a maximum means the graph doesnt exceed a point
hope this is right and helps :)
At first glance, it might be tempting to say this is a linear function, because we see linear terms (3x and –6x); however, these are multiplied together, so it's actually a quadratic.
We need to expand the function (hint: use FOIL) to identify the terms.

The x^2-term, or quadratic term, is

. The x-term, or linear term, is

. The number term, or constant term, is –20.
Answer:
the mean is 5
