Bonjour pouvez-vous m’aider s’il vous plaît merci

Réponse :

1) A = 5x+ 3

a) A = (5 x 10) + 3 = 53

b) A = (5 x -3) + 3 = -12

c) A = (5 x 3) + 3 = 18

2) B

a) B = (5 x 5) - (3 x 5) + 10 = 25 - 15 + 10 = 20

b) B = (-2 X -2) - (3 x -2) + 10 = 4 + 6 + 10 = 20

c) B = (2 x 2) - (3 x 2) + 10 = 4 - 6 + 10 = 8

3) C = -6x + 10

a) C = (-6 x 4) + 10 = -24 + 10 = -14

b) C = (-6 x5) + 10 = -30 + 10 = -20

c) C = (-6 x -5) + 10 = 30 + 10 = 40
