How can you use the graph of a linear equation to graph an inequality in two variables? You can graph the related linear equation as a dashed or solid boundary line, and shade the appropriate containing the solutions to the inequality.

The blank can either be plane or half-plane

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
