On donne les fonctions affines f et g définies par f(x) = 2x – 5 et g(x) = x + 2.
1) Construire dans un même repère les droites 1 et 2 les représentations
graphiques respectives de f et g.
2) Déterminer les réels x et y pour que A (2, y) et B(x, )
3) 1 coupe l’axe des abscisses en E .Calculer les coordonnées de E.
4) On pose C (4,3) et D (0,2). Vérifier que C 1 et que D 2.
5) On pose K milieu de [CD]. Calculer les coordonnées de K puis déterminer la fonction affine h qui
admet comme représentation graphique la droite (BK)

The management of a supermarket wants to adopt a new promotional policy of giving a free gift to every customer who spends more than a certain amount per visit at this supermarket. the expectation of the management is that after this promotional policy is advertised, the expenditures for all customers at this supermarket will be normally distributed with a mean of $95 and a standard deviation of $20. if the management wants to give free gifts to at most 10% of the customers, what should the amount be above which a customer would receive a free gift?
