a. How many days would it take for the patient's blood sample to have 480 antibodies? Show how you calculated your answer.

05) Simplifique as frações algébricas: (a) \( \left(16 x^{2}\right):\left(-4 x^{2}\right) \) (b) \( \left(36 x y^{2}\right):(-6 x y) \) (c) \( (-35 a):(+7 a) \) (d) \( \left(+3 a b^{2}\right):\left(-\frac{10}{5}\right) \) (e) \( \left(-\frac{4}{5} x^{2} y\right):\left(+\frac{4}{3} x^{2} y\right) \)

midpoint given the endpoints: \( (-1,5) \) and \( (-7,-7) \)

1. Frankie solved the equation below. Describe Frankie's mistake and record the correct olution. \[ \begin{array}{r}2.3 x-3.9+1.2 x-4.6=2 \\ 3.5 x-8.5=2 \\ 3.5 x=10.5 \\ x=7\end{array} \] ummarize today's lesson:

2. \( f(x)=x^{3} \) en \( a=1 \)

\( f(x)=\sqrt{ } x \) en \( a=3 \)
