Question

Determinati valorile reale ale parametrului m,stiind ca 2(5m+3) apartine [3;5].

Answer 1

m=3=> 2(5×3+3)=2(15+3)=2×18=36
m=4=> 2(5×4+3)=2(20+3)=2×23=46
m=5=> 2(5×5+3)=2(25+3)=2×28=56

Answer 2

2(5m+3)=3

10m+6=3

10m=3 - 6

m= - 3/10

2(5m+3)=4

10m=4 - 6

m= - 2/10= -1/5

2(5m+3)=5

10m=5 - 6

m= - 1/10
