Answer:
A, E
Step-by-step explanation:
You have to look for the ordered pairs where x (the first digit) doesn't repeat. that's a + e
3(3) - (-8)/4 = 9 + 2 = 11 so (3,-8) is solution
3(4) - 4/4 = 12 - 1 = 11 so (4,4) is solution
answer
C. both ordered airs are solutions
All the correct answers are C and D.
Hello from MrBillDoesMath!
Answer: The domain is the set of real numbers.
the full real number system
Discussion:
f(x) = (4/5)^x is defined for all x as the underlying function (4/5)^x is defined for all x. Therefore the domain is the set of real numbers.
Thank you,

Answer:
A. 37.5°
Step-by-step explanation:
∠SPT can be considered an inscribed angle in the circumcircle. In that circle, arc ST would have a measure of 360°/8 = 45°. Angle y° is half that measure, so is 22.5°.
The external angles of a regular octagon are 360°/8 = 45°, so that is the measure of angles UTW and UVW. It is also the amount by which reflex angle TUV exceeds 180°.
The sum of the interior angles of quadrilateral TUVW is ...
45° +225° +45° +3x° = 360°
Then 3x° = 45° and x° = 15°.
Then the sum of interest is ...
x° + y° = 15° + 22.5° = 37.5°
