Sagot :
Bonjour,
g(x) = -2/3x
g(-21) = -2/3 × (-21) = 42/3 = 14
g(3/7) = -2/3 × 3/7 = -2/7 (il suffit de supprimer les 3 pour simplifier la fraction)
Bonsoir,
g(x) = (-2/3)x
1. Calculer g(-21)
g(-21) = -2/3 * (-21)
g(-21) = [-21 * (-2)]/3
g(-21) = 42/3
g(-21) = 14 ✅
2. Calculer g(3/7)
g(3/7) = -2/3 * 3/7
g(3/7) = (-2 * 3)/(3 * 7)
g(3/7) = -6/21
g(3/7) = -2/7 ✅
* = multiplication
Bonne soirée
