Question

cine ma poate ajuta?

Answer 1

a) x+4<-3
=> x<-7 => x apartine {-8, -9, -10...}
b) -2x+1>= -3x+4-5x
=> -2x+1>= -8x+4
=> -2x+8x>= 3
=> 6x>= 3
=> x>=0.5 => x apartine {1,2,3,4,5,6...}
c) -5x+6 < -4
=> x>2 => x apartine { 3,4,5,6...}
d) 3x+5<= 4x+2
=> x>=3 => x apartine {3,4,5...}

La punctul e faci si singur. Nu imi place sa dau mura-n gura :)
