Answer:
B
Step-by-step explanation:
Hi there! The domain of a function refers to the values that can be validly input for x. In laymen's terms, domain is the x-values that exist on a graph of the equation.
If we were to plug in y=-2x+5 into a calculator that shows an infinite graph, we would see that the line of the equation would extend both ways infinitely! This means that all real numbers can be inputs for x, because for every x value that exists there is a corresponding y value.
This means that D. All real numbers, is your answer.
Hope it helps! :)

Answer:
B
Step-by-step explanation:
The arc XZ is twice the measure of the inscribed angle XYZ , that is
arc XZ = 2 × 60° = 120°
The complete circumference = 360° , thus
arc XYZ = 360° - arc XZ = 360° - 120° = 240° → B
Answer:
5
Step-by-step explanation:
6x^2 + 7x^3 + 8x^5 +9
Write in order from highest power to lowest power
8x^5 + 7x^3 + 6x^2 +9
The highest power ( largest exponent) is 5
The degree of the polynomial is 5
