<span>Plug in f(x) = 3 to solve

</span> $f (x) = -4x + 9$

$3 = -4x + 9$

$3-9=-4x$

$-6=-4x$

$-6/-4=x$

$6/4=x$

$3/2=x$

$x=3/2$

Can somebody do this without a calculator please?

$\frac{1}{f} = \frac{1}{u} + \frac{1}{v}$
multiply f to the entire equation
$1= \frac{f}{u}+\frac{f}{v}$
add up right side

$1=\frac{fv}{uv} +\frac{fu}{uv}$
$1= \frac{fv+fu}{uv}

$

multiply uv to both sides
$uv= fv+fu$
factor out f
$uv= f(v+u)$
divide (v+u) to both sides
$\frac{uv}{v+u}=f$

substitute in u=3.5cm and v=-4 cm

Answer:

Step-by-step explanation:

Since AP and BP are tangents from the same point, they are equal. So 2x+12=4x-8. So solving for x, we get 2x=20. So x=10. Plugging that in, we get 20+12=32. So the answer is 32.
