I'm a bit lost on this.<br><br> What is f(-6)?

quester [9]

F(-6) is the point where the line hits -6 on the x axis, which in this case is (-6,6). It's easier to think of a line as an equation; this line would be f(x) = |x|. Absolute value is the magnitude of a number without regard to its sign, so the absolute value of -6 is 6, because you're ignoring the negative sign. I hope this helps you with future problems!

Need help I'm getting it wrong I don't understand

ivanzaharov [21]

W/3-15=12
remember, you can do ANYTHING to an equaiton as long as you do it to both sides
get w by itself

$\frac{w}{3}-15=12$
add 15 to both sides
$\frac{w}{3}+15-15=12+15$
$\frac{w}{3}+0=27$
$\frac{w}{3}=27$
tiemes both sides by 3/1
$\frac{3w}{3}=27*3$
$(\frac{3}{3})w=81$
$1w=81$
$w=81$
