Which statements are true about the ordered pair (10, 5) and the system of equations? {2x−5y=−5x+2y=11

Select each correct answer.

A.
The ordered pair (10, 5) is a solution to the first equation because it makes the first equation true.

B. The ordered pair (10, 5) is a solution to the second equation because it makes the second equation true.

C. The ordered pair (10, 5) is not a solution to the system because it makes at least one of the equations false.

D. The ordered pair (10, 5) is a solution to the system because it makes both equations true.

Acable company wants to provide cell phone service for residents on an island. the function for the cost of laying the cable from the island to the mainland is c(x)= 6.500 square root x2+4, where x represents the length of the cable in feet. what are the domain and range of the function? a) domain: all real numbers range: all real numbers greater than or equal to 17,000 b) domain: all real numbers greater than or equal to 0 range: all real numbers greater than or equal to 17,000 c) domain: all real numbers greater than or equal to 0 range: all real numbers greater than or equal to 13,000 d) domain: all real numbers greater than or equal to 13,000 range: all real numbers greater than or equal to 0

The equation of a circle is (x + 4)2 + (y + 6)2 = 16. determine the length of the radius. 10 4 16 8 my flower basket delivers flowers within a 20 mile radius of their store. if this area is represented graphically, with my flower basket located at (5, 2), what is the equation that represents the delivery area? (x - 2)2 + (y - 5)2 = 20 (x - 5)2 + (y - 2)2 = 20 (x + 5)2 + (y + 2)2 = 400 (x - 5)2 + (y - 2)2 = 400
