Question

Solve x9+3≤11
. Graph the solution(1 point)

Answer 1

I assume you mean x^9 + 3 ≤ 11.

Solve:
x^9 + 3 ≤ 11
x^9 ≤ 8
Since the ninth power is increasing for real x, take the ninth root:
x ≤ 8^(1/9) = 2^(1/3) ≈ 1.26

Solution in interval form: (-∞, 2^(1/3)].

Graph (number line): closed dot at 2^(1/3) (≈1.26) and shade to the left.

1.26

If you instead meant 9x + 3 ≤ 11, then x ≤ 8/9.
