The equation (x – 5)2 + (y – 7)2 = 81 models the position and range of a cellular phone tower. What is the range of the tower?

A: 18 units

B: 9 units

C: 27 units

D: 81 units

1 + (6 / x - 1)

step-by-step explanation:

divide using polynomial division.

m∠a is 90°

m∠b is 40°

step-by-step explanation:

graph b

step-by-step explanation:

one solution- graph a (clear intercepting point.)

no solution- graph b (they're parallel, there will never be a point of interception.)

infinite solutions- graph c (all points intercept.)
