Answer:

= { \tt{(0, \: 0)}}

Step-by-step explanation:

Let:

{ \bf{ - x - 2y = 0 -  -  - (a)}} \\ { \bf{y =  - 8x -  -  - (b)}}

Substitute for y in equation (b) to equation (a):

{ \tt{ - x - 2( - 8x) = 0}} \\ { \tt{ - x + 16x = 0 }} \\ { \tt{x = 0}}

Also, y = 0

I need a bit of help here.
kotykmax [81]

Answer:

Beginning in the 6th century BC with the Pythagoreans, the Ancient Greeks began a systematic study of mathematics as a subject in its own right with Greek mathematics. Around 300 BC, Euclid introduced the axiomatic method still used in mathematics today, consisting of definition, axiom, theorem, and proof.

Step-by-step explanation:

The first recorded zero appeared in Mesopotamia around 3 B.C. The Mayans invented it independently circa 4 A.D. It was later devised in India in the mid-fifth century, spread to Cambodia near the end of the seventh century, and into China and the Islamic countries at the end of the eighth.
