What is the solution to the following system of equations? {x+y=5)
{x+y=1
(–2, 7)
(2, 3)
(3, 2)
(7, –2)

it would be 2 or b because the clouds are a form of condensation

radiative zone

explanation    

radiative zone is the layer of the sun which energy is transferred away from the core by radiation. although, the core is the only part of the sun that produces an appreciable amount of heat through fusion. in fact, 99% of the energy produced by the sun takes place within 24% of the sun's radius.
