divide and , if possible, simplify:
Divide and, if possible, simplify. \[ \frac{b-5 a}{b^{2}+10 b a+25 a^{2}} \div \frac{b^{2}-25 a^{2}}{b^{2}-7 b a+10 a^{2}} \]1 answer -
define the exercises 12, 13,15 , whether it is a function or not a function
11. \( x+y=16 \) 12. \( x+y=25 \) 13. \( x^{2}+y=16 \) 14. \( x^{2}+y=25 \) 15. \( x^{2}+y^{2}=16 \) 16. \( x^{2}+y^{2}=25 \) 17. \( x=y^{2} \) 18. \( 4 x=y^{2} \) 19. \( y=\sqrt{x+4} \) 20. \( y=-\sq1 answer -
(2 points) Let \( x, y, z \) be (non-zero) vectors and suppose \( w=4 x-6 y+3 z \). If \( z=3 y-2 x \), then \( w= \) \( x+ \) \( y \). Using the calculation above, mark the statements below that must2 answers
