Determine if the expression for r(u, v) with domain d defines a smooth parametrized surface. explain your answer. (your instructors prefer angle bracket notation < > for vectors.) r(u, v) = cos(u), sin(v), 1 , d = {(u, v) | 0 ≤ u ≤ 4π, 0 ≤ v ≤ 4π}

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
