Geometry question about finding missing angles!

Step-by-step explanation:

The sum of the three angles is 180°.

  (2x) +(x+y) +(52-2y) = 180

  3x -y = 128 . . . . write in standard form

The congruent angles have equal measure.

  2x = 52 -2y

  x + y = 26 . . . . write in standard form

__

Adding these two standard-form equations, we get ...

  (3x -y) +(x +y) = (128) +(26)

  4x = 154

  x = 38.5

  x + y = 26

  y = 26 -38.5 = -12.5

The values of interest are ...

a

step-by-step explanation:

the answer is a

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
