calculate the cross elasticity of demand for good X when the price of good z increases from RM2.50 to RM3.00 . State the relationship between Z and X

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

false

step-by-step explanation:

false : it can not go to 9 the highest that part can go is 7

here is your proof

cool? what is the actuall ?

step-by-step explanation:

      2

  2 is to go somewhat to the top right of a because it is squared    

v= a h/3
