Answer:
D
Step-by-step explanation:
The cost(y) of producing x number of balls is given by the linear model y = 3.25x + 685000
Linear equation
A linear equation is in the form:
y = mx + b
where y, x are variables, m is the rate of change (slope) and b is the y intercept.
Let y represent the cost of producing x number of beach balls.
Using the point (10000, 587500) and (50000, 717500):

The cost(y) of producing x number of balls is given by the linear model y = 3.25x + 685000

Answer: D) The relation R is a function because for each input there is exactly one output
There's not much else to say other than what choice D already does. Visually we can use the vertical line test to confirm if we have a function or not. If we can pass a single vertical line through more than one point on a curve, then the curve isn't a function. The graph is said to have failed the vertical line test. Otherwise, the relation passes the vertical line test and we have a function.
(4/9) divided by (2/3) is 2/3 because you do the reciprocal and mul. Then you mult it by the reciprocal of (5/6) which is (6/5) and get 4/5
