Answer:
(-4,3)
Step-by-step explanation:
The domain of a function is all of its possible x-values. In this graph, there is a y-value for every x-value between -4 and 3 except -4 and 3, because there are open dots at those points. Therefore, the domain is (-4,3). Use parenthesis because the function is not defined at x=-4 or x=3.
Answer:
(x² -1) + y² = 9
Step-by-step explanation:
diameter=6 so radius means 6/2=3 (thus,radius²=3²=9)
centre (1 and midpoint of diameter is at y=0, so 1,0)
I think D is the correct answer.
The average cost per cleaning service call charge by the company is $184.5.
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Let y represent the total cost for x number of service calls in a year. Hence:
y = 39x + 349200
For 200 service call, in a year, x = 200 * 12 = 2400
y = 39(2400) + 349200 = $442800
Average cost = $442800 / 2400 = 184.5
The average cost per cleaning service call charge by the company is $184.5.
