If -18 greater or equal to 6-12ax, which inequality represents the possible range of values of 1-2ax

1-2ax is less than or equal to -3

So 1-2ax can be -3 or smaller

============================================

Work Shown:

Factor out 6

Divide both sides by 6

Flip the two sides, and the inequality sign

step-by-step explanation:

∆abc has the points a(1, 7), b(-2, 2), and c(4, 2) as its vertices. formed with the point d(1, 2) as its third vertex, then ∆abd is triangle.
