Question #2c599 Algebra Graphs of Linear Equations and Functions Direct Variation 1 Answer MeneerNask Apr 23, 2017 So we know that #root 3x=cxxy^2# where #c=# a constant. Explanation: Plug in what we know: #root3 27=cxx3^2->3=cxx9->c=3/9=1/3# Now the new value of #y#: #root3x=1/3xx1.5^2=1/3xx2.25=0.75=3/4# #->x=(3/4)^3=27/64~~0.42# Answer link Related questions What is Direct Variation?
