Answer:
The ordered pair is (3, 2).
Step-by-step explanation:
y = -x + 5
2x + y = 8
Substitute y = -x + 5 in the second equation:
2x + (-x + 5) = 8
x + 5 = 8
x = 3.
Now substitute x = 3 into the first equation;
y = -3 + 5
y = 2.

Answer:
Step-by-step explanation:
The square root of 2 is irrational, the square root of 3, 5, 6, 7, 8, 10, and any other positive number that is not a perfect square. You can find more by dividing an integer by an irrational number. (5 / sqr rt of 2...)
There are more irrational numbers than there are rational numbers. There are aleph-null rational numbers and aleph-one irrational numbers. (Aleph-null is the smallest size of infinity, aleph-one is the second size.)
