• LINEAR EQUATIONS AND INEQUALITIES–

347.The graphs of the lines 5x– 2(y+ 10) = 0 and
2 x+ y= –3 form the boundaries of the shaded
region. The solution set of which of the follow-
ing systems of linear inequalities is given by the
shaded region?

a. 5 x– 2(y+ 10)0, 2x+ y–3

b. 5 x– 2(y+ 10)0, 2x+ y–3

c. 5 x– 2(y+ 10) 0, 2x+ y –3

d. 5 x– 2(y+ 10) 0, 2x+ y –3

348.The graphs of the lines 7(y– 5) = –5xand

–3 = ^14 (2x– 3y) form the boundaries of the
