Answer:
4% of all adults go to a health club at least twice a week
Step-by-step explanation:
the proportion of adults who belong to health clubs is 10% that is 0.10
the proportion of these adults (health club members) who go to the club at least twice a week is 40%, which is 0.40.
Thus, the proportion of all adults who go to a health club at least twice a week is
0.10 × 0.40 = 0.04, that is 4%

EXPLANATION
The first equation is
![y = {x}^{2} - 2x](https://tex.z-dn.net/?f=y%20%3D%20%20%7Bx%7D%5E%7B2%7D%20%20-%202x)
and the second equation is
![y = - 2x - 1](https://tex.z-dn.net/?f=y%20%3D%20%20-%202x%20%20-%201)
We equate the two equations to obtain;
![{x}^{2} - 2x = - 2x - 1](https://tex.z-dn.net/?f=%20%7Bx%7D%5E%7B2%7D%20%20-%202x%20%3D%20%20-%202x%20-%201)
This implies that
![{x}^{2} = - 2x + 2x - 1](https://tex.z-dn.net/?f=%20%7Bx%7D%5E%7B2%7D%20%20%3D%20%20-%202x%20%2B%202x%20-%201)
![{x}^{2} = - 1](https://tex.z-dn.net/?f=%20%7Bx%7D%5E%7B2%7D%20%20%3D%20%20-%201)
There is no real number whose square is -1.
Therefore, the equation has no solution.
