Writing \( \log _{a} x-\log _{a} y+8 \log _{a} z \) as a single logarithm results in which of the following expressions? Choose the correct answer below. \( \log _{a}\left(\frac{x}{y z^{8}}\right) \) \( \log _{a}\left(\frac{x z^{8}}{y}\right) \) \( \log _{a}(x-y+8 z) \) \( \log _{a}\left(\frac{8 x z}{y}\right) \)

[-/2 Points] DETAILS MY NOTES TGEIALG6 2.5.053. The perimeter of a regulation singles tennis court is 210 feet and the length is 3 feet less than three times the width. What are the dimensions (in ft ) of the court width length

A. Déterminer la forme canonique de chacun des polynômes suivants : 1. \( P(x)=3 x^{2}-6 x+9 \) 2. \( P(x)=-5 x^{2}+3 x+12 \) 3. \( P(x)=9 x^{2}-7 x \)

(b) \( 27 x^{2}-3 y^{2} \)

Verifique se a equação abaixo é ou não é uma proporção \( \frac{2-2 x}{3 x}=-\frac{1}{3} \)

Use the point-slope form to write an equation of the line with the given slope and point. Then write the equation in slope-intercept form. slope 4 , passes through \( (4,6) \)
