4) If A = {1,2,3,4} then the relation on AXA where R = {(1,1)(1,2)(2,1)} a) {(x, y): y = 2x) b) {(x, y); x+y=1} c) {(x, y); x+y< 3} d){(x, y); x+y< 4}​

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

step-by-step explanation:

total income = price of one ticket   *   number of tickets sold

  y                 =     4                                   x

so the equation is y=4x     with x≥0   because number of tickets sold can not be negative

thus the equation is a semi -line with an end point at

(0,0)

passing through :

x=1     y=4(1) = 4   so through (1,4)
