Total cost including delivery cost: $6600 + $60 = $6660



Answer:
D) 5x + 6y = 12
Step-by-step explanation:
x = y^2 is Not Linear (Find the degree of the equation to determine if linear.)
y - 2 = x^(2) + 5x is Not Linear (Find the degree of the equation to determine if linear.)
y = x^(3) + 1 is Not Linear (A linear equation is an equation of a straight line, which means that the degree of a linear equation must be 0 or 1 for each of its variables. In this case, the degree of variable y is 1 and the degree of variable x is 3.
5x + 6y = 12 is Linear (Find the degree of the equation to determine if linear.)
