N means 2 matches because half of 10 is 5 and they've won 3 matches so they need to win 2 more matches.
Independent variable - represents a quantity that is being manipulated
dependent variable- represents a quantity whose value depends on how the independent variable is manipulated.
-5.2 -4.8= -10 thats your answer and it easy math.
The standard equation of a parabola is:
(y-k) = a(x - h)² , where h and k are the coordinates of the Vertex
Since the vertex is ( - 5 , -7), then :
(y +7) = a (x + 5)².
It's given that the vertex is a minimum, that means the coefficient a>0 and the parabola is open upward.
Depending on the value of a (always a>0) , the equation :
y = a(x-5)² + 7 is a parabola
Answer:
Step-by-step explanation:
We have been given the equation:
And 
Second equation can be rewritten as:
We will solve the equations:
(1)
(2)
Multiply equation (1) by 5 and equation (2) by 3 we get:
(3)
(4)
Now, subtract (4) from (3) we get:
Now substitute in equation (1) we get:
