Answer:
x = -1
Step-by-step explanation:
With the axis of symmetry, think of it as where you would slice this line in half, and both sides would look identical to each other. Since this is a quadratic function, this would be at where the vertex is.
The vertex is the part of the line where it "turns" around and starts going the other way. So vertex of this line is at (-1, 3).
Therefore, the axis of symmetry is at x = -1. This is since the function is pointing either up/down, and any value that is x = _ is a vertical line.
Answer:
The correct choice is option D. y = 2x -12
Step-by-step explanation:
slope of the points (5,-2) and (8,4) is m = 2
y — intercept of the points (5,-2) and (8,4) is b = -12
Now, put it all together, and you'll get : y = 2x -12
Answer:
B When the sales are 12, the profit is 400.
Step-by-step explanation:
Given
Required
Interpret the intersection
From the intersection, we have the following parameters.
Literally, it means
when
From the question, we understand that
s represents sales while p, profit.
So, the interpretation of is when sales = 12, profit = 400
Answer:
Step-by-step explanation:
If M is the midpoint of AB, then AM = MB
Also AM+MB = AB
MB+MB = AB
2MB = AB
2MB = 6
MB = 6/2
MB = 3 cm
Also
If M is the midpoint of CD, then CN = DN and CN+DN = CD
CN+CN= CD
2CN = CD
2CN = 6
CN = 6/2
CN = 3 cm
Note that MN = MB + BC + CN
Substitute the given data
MN = 3cm + 6cm+3cm
MN = 12cm
Therefore the distance between M and N is 12cm
