Answer:
$12,000,000
Step-by-step explanation:
The maximum will be the vertex and because this is written in vertex form the vertex will be (5, 12) so the maximum income will be 12 million dollars.
Given:
M(4,2) is the midpoint of AB and A(-5, -3).
To find:
The coordinates of B.
Solution:
Let the coordinates of point B are (a,b).
Midpoint formula:
M(4,2) is the midpoint of AB and A(-5, -3).
On comparing both sides, we get
And,
Therefore, the coordinates of point B are (13,7).
Answer: y = -2x
Step-by-step explanation:
Hello!
We need to know that if two lines are parallel, then their slopes must be equivalent. This means that the new equation has a slope of -1.
Also, to find the equation that contains the point (3, -2), we need to substitute that ordered pair with the original slope into the equation to find the y-intercept.
As a reminder, slope-intercept form is y = mx + b. In this equation, m is the slope and b is the y-intercept.
-2 = -1(3) + b
-2 = -3 + b (add 3 to both sides)
1 = b
Therefore, the equation of the line is y = -x + 1.
