Which statement is true about f[x]= 2/3 |x+4| -6? the graph of f(x) has a vertex of (–4, 6). the graph of f(x) is a horizontal stretch of the graph of the parent function. the graph of f(x) opens upward. the graph of f(x) has a domain of x< _
–6.

you can not solvr this without numbers

given the equation is 8+9z=-6, the first step would be to subtract the 8 from both sides:

8+9z-8=-6-8

since 8 minus 8 = 0, this would cancel out the 8. and since -6 minus 8 equals -14, the equation would look like this

9z = -14
