2) Are these two models equivalent? Model 1: Function
f(x) = 1/3x - 2
Model 2: Graph
a) Yes, because they are increasing,
b) Yes, because they have the same common difference, d =
c) No, because they are increasing.
d) No, because they have different common differences.

It is probably 2+4=7-1=6

(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
