A custodian went to buy x boxes of cleaning supplies and y boxes of light bulbs. He had the back of a van to transport them. Given a maximum amount that he could spend, and a limited space to put the supplies in, the following system of inequalities and graph represent the constraints. LOOK AT SCREENSHOT FOR THE GRAPH

Which of the following points represent real solutions for this situation? Select all that apply.

(0, 40)
(30, 20)
(37.5, 15)
(50, 5)

given hc ∥ gd.¯¯¯¯¯¯which statement is true

step-by-step explanation:

∠cbe and ∠deb are same-side interior angles

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.
