Given the figure below, find the values of x and Z. Please explain step by step how to solve, this is a guide for a test.

  (x, z) = (7, 69)

Step-by-step explanation:

Easy first: 69° and z° are vertical angles, so congruent:

  z = 69

__

The angle marked with an expression in x is supplementary to either of the other two:

  (6x +69)° +69° = 180°

  6x = 42 . . . . . . . . . . . . divide by °, subtract 138

  x = 7 . . . . . . . . . . . . . . divide by 6

sup

step-by-step explanation:

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.

hope i !
