URGENTEE ME AJUDEMM RAPIDOO PFF​

Answer 1

Resposta:

A → $x < -8$

B → $x\leq 14$

C → $x\leq \frac{12}{7}$

D → $x > -\frac{8}{7}$

Explicação passo-a-passo:

A.

$2x+3<-5+x\\\\2x-x<-5-3\\\\x<-8$

B.

$4(x+6)\geq 5x+10\\\\4x+24\geq 5x+10\\\\4x-5x\geq 10-24\\\\-x\geq -14\\\\x\leq 14$

C.

$\frac{x}{3} + \frac{x}{2} \leq \frac{x}{4} + 1\\\\4x+6x\leq 3x+12\\\\10x\leq 3x+12\\\\10x-3x\leq 12\\\\7x\leq 12\\\\x\leq \frac{12}{7}$

D.

$4x + 6(x+1) > -2 + 3x\\\\4x+6x+6>-2+3x\\\\10x+6>-2+3x\\\\10x-3x>-2-6\\\\7x>-8\\\\x> -\frac{8}{7}$

Espero ter ajudado :)
