x^2 = 800. Take the square root of each side.
x = √(800) and -√(800)
Answer:
The ordered pair that makes an equation true is called a solution
a)solution
b) not a solution
c) solution
d) solution
e)not a solution
f) not a solution
g) solution
h) not a solution
Step-by-step explanation:
The first number in an ordered pair is x, the second one is y
Plug in the numbers to x and y respectively
I'll give two examples so you know how to solve it
a) y=3x+1
-5=3(-2)+1
make sure you use pemdas (multiply first)
-5=-6+1
add
-5=-5
this is true (meaning it is a solution)
b) 6=3(-3) +1
6=-9+1
6 = -8
this is NOT true (not a solution)

The fact that it takes Earth 365 days to move year in and year out has been known for many centuries. Even before heliocentric and geocentric models were introduced, people were already familiar with the 365 day period. Perhaps Galileo would be the answer, but hasn't been truly defined as to who first observed this.
