Step-by-step explanation:
By equating both quadratic equations, Brian can determine the point of intersection of both equations. Upon graphing he was able to identify that both share the same vertex but of opposite opening. Based on this, he can say that both equations are equations of parabolas with same vertex but open on different directions.
Answer:
x^2 - 5x + 4.
Step-by-step explanation:
(p - q)(x) = x^2 - 1 - (5x - 5)
= x^2 - 5x - 1 + 5
= x^2 - 5x + 4.
Answer:
Cliff get £36
Step-by-step explanation:
Alan, Barry and Cliff share money in the ratio 1:4:6
Alan and Barry share £30.
So, let they share 1 x ,4 x.
We can set up equation as 1 x+4 x=30
Combine like terms 5 x=30
Divide both sides by 5.
x=6.
So, Cliff will get 6 x=6(6)= 36.
