Ms. Rodriguez showed her Students how to solve this system of a question y=2x-1 y=4x+1 she found the equation of (-1,-3)
what does this mean

4th option is correct xy=-10

if this was to u plzz mark me the brainliest

ratio is 2 : 9

the answer is three

13.5 : 3

27/4x^6 y^8

step-by-step explanation:

4(3x^2y^4)^3 (2x^3y^5)^4

=

108x^6 y^12 /16x^12 y^20

=

108 /16x^6 y^8

=

27 /4x^6 y^8

answer is 1
