Step-by-step explanation:
The computation of the number of people in the chorus are 50 or older is as follows
According to the attached figure
In the age of 50 - 60 , there is 8 people
In the age of 60 - 70 , there is 4 people
In the age of 70 -80, there is 1 people

Answer:
(-3,0) ; (1,0)
Step-by-step explanation:
We have to solve the associated equation:
-2x^2 -4x + 6 = 0
-x^2 - 2x + 3 = 0
x^2 + 2x -3 = 0
Δ/4 = 1 + 3 = 4
x1 = -1 + 2 = 1
x2 = -1 -2 = -3
