True or False
A proportional
relationship can have a
positive or negative unit
rate.

Technically two quantities are proportional if one is always a constant multiple of the other, and from a strictly mathematical point of view, there is nothing to stop the constant from being negative. ... On the other hand, it isn't hard to come up with examples where you could use a negative proportion

step-by-step explanation:

(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
