Answer:
The vertex for each quadratic is 
Step-by-step explanation:
To determine the vertex for each quadratic,
The vertex of the 
coordinate can be determined using the formula,
The standard form of the quadratic function is
Hence, for the given equation of the quadratic function,
and 
Hence, 
becomes,
∴
This is the vertex for the 
To determine, the vertex for the 
We will put the value of the vertex of the in the equation and write
Then,
This the vertex for the
Hence,
Answer:
N = 24
Step-by-step explanation:
24 - 4 = 20
Answer:
x = √(-1) = i
Since the value of √(-1) is not real.
The system has no real solution.
Step-by-step explanation:
The solution to the system of equations is at the point where they intercept each other.
y1 = y2
For the given equation;
y=x^2-2x and y=-2x-1
To get the where they intercept, we will equal both equations;
y=x^2-2x = -2x-1
x^2 - 2x = -2x - 1
x^2 - 2x + 2x + 1 =0
x^2 +1 = 0
x^2 = -1
x = √(-1) = i
Since the value of √(-1) is not real.
The system has no real solution.
The range is [4,∞)
Or from 4 to positive infinity
Or y is greater than or equal to 4
Answer:
Mean= 4
Median= 3
Step-by-step explanation:
Mean
add all the numbers together (24)
and divide them by the number of numbers (6)
gives you 4
Median
put them in order from least to greatest
2,2,2,4,7,7
2,2 2,4 7,7
it leaves you between 2 and 4
which the middle is 3
so there
