Answer:
These patterns recur in different contexts and can sometimes be modelled mathematically. Natural patterns include symmetries, trees, spirals, meanders, waves, foams, tessellations, cracks and stripes. Early Greek philosophers studied pattern, with Plato, Pythagoras and Empedocles attempting to explain order in nature.

Answer:
x=9
y=12
Step-by-step explanation:
. Substitute the given value of x into the equation so... -5(2y-15)+4y=3
. y=12
. Substitute the given value of y into the equation x=2y-15 so... x=2 x 12-5
. x=9
.The possible solution of the system is the ordered pair (x,y) so... (x,y)=(9,12)
Answer:
-60.X + 32 = 32.r – 60
Because we only have one equation for 2 unknowns.
Step-by-step explanation:
All the equations have solution for r but the one that has 2 unknowns (r and X).
That is because we only have one equation and 2 unknowns.
Then, we only can express one unknown in function of the other and have an indeterminate solution.
