Use interval notation to represent all values of x satisfying the given conditions.
Y1=X/3+4, y2= x/4+9/3, and y1 <(with the _ in the bottom of it) y2
first to answer correctly will be chosen as best answer.
Y1=X/3+4, y2= x/4+9/3, and y1 <(with the _ in the bottom of it) y2
first to answer correctly will be chosen as best answer.

y₁ = x/3 + 4
y₂ = x/4 + 9/3 = x/4 + 3
y₁ ≤ y₂
x/3 + 4 ≤ x/4 + 3
x/3 − x/4 ≤ 3 − 4
x/12 ≤ −1
x ≤ −12
In interval notation: (−∞, −12]
