Answer:
If x is an integer, then for values of x ≤ 0 would -x be positive.
General Formulas and Concepts:
<u>Math</u>
Step-by-step explanation:
We know that integers comprise of the number line from -∞ to ∞. We can have numbers like -3, -2, -1, 0, 1, 2 ,3.
If we say that x is an integer, and that -x must be positive, then that means the integer x must be negative, because a negative times a negative is a positive.
∴ x can only be negative integers, thus giving us x ≤ 0.

Answer:
f(2)= 5
Step-by-step explanation:
Given f(x) = -x² + 1
f(2) = -2² + 1 = 4 + 1 = 5
f(2) means the value of x = 2
Hence we substitute the value of X into f(x) = -x² + 1
The answer is 12 it makes every fraction into a whole number
We can use the Pythagorean theorem to solve. (a² + b² = c²)
Fill in with what we know → 6² + b² = 11²
Simplify → 36 + b² = 121
Subtract 36 to both sides → 36 - 36 + b² = 121 - 36
Simplify → b² = 85
Take the root of both sides → √b² = √85
Simplify → b = 9.2195...
Round if necessary → 9.2195 = 9.22
Hence, b equals 9.2195.. (unrounded) or 9.22 (rounded).
Best of Luck!
