Anton delivers pizzas for Grizzly's Pizza. In one night, he delivered image different orders. He checks each pizza stacked on the top of each order to make sure that they have not been damaged in the trip. In doing this, he finds that image of them are cheese. What is the best estimate that can be made about the number of cheese pizzas sold at Grizzly's Pizza?

$15 each

step-by-step explanation:

$45/3 children= $15 each

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.

step-by-step explanation:

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7
