Question

Calculati A intersectat cu B, stiind ca A={x| x apartine R, 2 mai mic sau egal decat x+5<6}
Iar B={x| x apartine R, |2x-1| mai mic sau egal decat 3}

Answer 1

2<=x+5<6/-5
-3<=x<1
x∈[-3,1)

-3<=2X-1<=3/+1
-2<=2X<=4/:2
-1<=X<=2
X∈[-1,2]=B
[-3,1) INTERSECTAT [-1,2]=[-1,1)
sper ca te-am ajutat!
