Question

Help, help, help I can’t get these

Answer 1

$\bf f(x) = -\cfrac{1}{4}x+3\qquad \qquad \stackrel{f(x)}{x}= -\cfrac{1}{4}x+3\implies x = -\cfrac{x}{4}+3\implies x-3=\cfrac{-x}{4} \\\\\\ 4x-12=-x\implies 5x-12=0\implies 5x = 12\implies \boxed{x = \cfrac{12}{5}}$

Answer 2

If we don’t end up helping you, just remember that you can always ask you parent/guardian or teacher. They all want to help you in anyway hey can.
