43n^2-54. then do the exponent part your self! :)
The number will be itself when multiplied by 1.
The sum of twice and half the original number is 1, so the number is
2n +0.5n = 1
2.5n = 1
n = 1/2.5 = 0.4
The original number is 2/5.
Step-by-step explanation:
plug y value :
10=1/2x+8
1/2x=2
x=4
It can be a decimal or fraction. An integer HAS to be a whole number.
-2, 10, and 4300 are integers
8.4, -0.14568, and 1/2 are not integers
