Which of the following represents the characteristics of the graph of x ≤ -7?

open circle on -7, shaded to the right.
closed circle on -7, shaded to the left.
open circle on -7, shaded to the left.
closed circle on -7, shaded to the right.

B

Step-by-step explanation:

Since x ≤ - 7 , that is less than or equal to, then

closed circle on - 7 representing equality of - 7

Since values are less than - 7 then line is shaded to the left

10a^3+277a^2-132a-792

step-by-step explanation:

(2a+11)(5a-12)(foil)

=10a^2-24a+55a-132 =10a^2+31a-132

(10a^2+31a-132)(a+6)

=10a^3+60a^2+31a^2+186a^2-132a-792 =10a^3+277a^2-132a-792

i hope this is what you are looking for : )

< 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
