Graph the following system of linear inequalities. identify at least two points in the solution: y < 5 - 2x | x + 5y > -7

(1,2) and (2,-1)

Step-by-step explanation:

we have

----> inequality A

The solution of the inequality A is the shaded area below the dashed line

----> inequality B

The solution of the inequality B is the shaded area above the dashed line

The solution of the system of inequalities is the shaded area between the two dashed lines

If a ordered pair is a solution of the system of inequalities, then the ordered pair must lie on the shaded area

Two points in the solution are

(1,2) and (2,-1)

see the attached figure

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30
