Re
y
y + 10
5 ( y + 10 )
= 5 y + 50
p (9) = 45 + 50 = 95
p ( - 11 ) = - 55 + 50 = - 5
p ( 6/5 ) = 30/5 + 50 = 6 + 50 = 56
5 y + 50 = 0
5 y = - 50
y = - 10
Explications étape par étape :
P(y) = 5(y+10)
2)
P(9) = 5*19 = 95
P(-11) = 5*(-1) = -5
3) P(6/5) = 5(6/5 + 10) = 5(6/5 +50/5) = 5(56/5) = 56
5) 5(y+10) = 0
Alors y + 10 = 0
y = -10
2)
P(9) = 5*19 = 95
P(-11) = 5*(-1) = -5
3) P(6/5) = 5(6/5 + 10) = 5(6/5 +50/5) = 5(56/5) = 56
5) 5(y+10) = 0
Alors y + 10 = 0
y = -10
