Answer:
B
Step-by-step explanation:
Solve each inequality separately
2x + 3 ≥ 7 ( subtract 3 from both sides )
2x ≥ 4 ( divide both sides by 2 )
x ≥ 2
or
2x + 9 > 11 ( subtract 9 from both sides )
2x > 2 ( divide both sides by 2 )
x > 1
x ≥ 2 satisfies the condition for both inequalities
Thus x ≥ 2 is the solution
