Check the picture below, that's a parabolic graph of a quadratic equation with a negative leading coeffficient, like this one, the one in the graph is just for initial velocity, but, the highest point is at the vertex for any of these parabolas.
and this one is not exception, so where's the vertex? what's A or the y-coordinate when the vertex is reached?, well, let's check.

so, that's the vertex, and when the width is that much, the Area reaches a maximum of that much.
Answer:
(-0.6 , -5.2)
Step-by-step explanation:
4x-2y=8
y=12x+2
just graph the line of each equation of the system and then locate the
intersection point
the coordonates of that point are pair solutio to the system
check the picture below for the graph.
:)
Answer:
Y=x+5
Step-by-step explanation:
slope of 1 y intercept of 5
Answer:
The answer to your question is (34 + 10i)
Step-by-step explanation:
Data
(21 + 2i) + (13 + 8i) =
To solve this operation, just sum up the whole numbers and get a result then, sum up the imaginary numbers and get another result. Finally, write the result.
-Whole numbers 21 + 13 = 34
-Imaginary numbers 2i + 8i = 10i
Result (34 + 10i)
