Answer: First option, the graph of the relation passes the vertical line test.
Step-by-step explanation:
A function is a relation that maps elements from a set (the domain, the x-values) into elements from another set (the range, the y-values)
Where the only condition we have is that each element from the domain can be mapped into only one element from the range.
So if we draw a vertical line at any point of the graph, it can intersect the graph of the function a maximum of one time. (this is known as the vertical line test)
Then the correct option is that the graph of the relation passes the vertical line test.
I can’t help you but here are some notes I took on the topic
Answers:
- Sarah has $12.50
- Sam has $27.50
- Casey has $55
======================================================
Explanation:
x = amount of money Sarah has
x+15 = amount of money Sam has, since he has $15 more than her
2(x+15) = amount of money Casey has, since he has twice as much as Sam.
Let's add up those three expressions and set that sum equal to 95
Solve for x.
Sarah + Sam + Casey = 95
x+(x+15) + 2(x+15) = 95
x + x + 15 + 2x + 30 = 95
4x+45 = 95
4x = 95-45
4x = 50
x = 50/4
x = 12.50
This says that Sarah has $12.50
That must mean Sam has x+15 = 12.50+15 = 27.50 dollars
And Casey must have 2*27.50 = 55 dollars.
----------------
As a check,
Sarah+Sam+Casey = 12.50+27.50+55 = 95
So the answer is confirmed.
