The number of views of an online video grow 10 times everyday. When the video was posted there were 8 views. 1. Let \( y \) be the number of views, and \( x \) be the number of days that the video has been posted, write an equation that represents the number of views over time. 2. Today the video had \( 8,000,000,000,000 \) views. How many days has the video been online since it was posted?

Diketahui matriks \( M=\left[\begin{array}{ccc}3 & 0 & -2 \\ -5 & 2 & 0 \\ 0 & -3 & 4\end{array}\right] \) dan \( N=\left[\begin{array}{ccc}0 & 7 & 5 \\ 5 & -3 & 2 \\ 0 & -4 & -3\end{array}\right] \) adalah matriks berordc 3x3. Jika \( \mathrm{M}+\mathrm{N} \), maka tentukanlah hasil dari penjumlahan kedua matriks tersebut !

4. Realiza las operaciones indicadas y simplifica el lesultado: \( \begin{array}{ll}\text { A) } \frac{x^{2}-64}{2 x^{2}+16 x}= & \frac{\text { B) } 3 x-9}{x^{2}-9 x+18}=\end{array} \)

3Ldentifica y realiza los siguentes productos notables de polinomios: \( \begin{array}{ll}\text { A) }(2 a b+7 c)(2 a b-7 c)=\quad & \text { b) }(5 a-2 b)^{2}=\end{array} \)

Jason earns an hourly wage of \( y \) dollars. If he works \( h \) hours in a week, write a linear expression representing his weekly earnings.

a. \( \quad(6 x-18)(3 x+2)=0 \)
