8xy^2 - 3xy^2 = 5xy^2
7xy^2 - 2xy^2 = 5xy^2
Answer:
6
Step-by-step explanation:
you start with 30.00
the colf costs 12.00 so 30.00-12.00=18.00/3
6
Turn hours into minutes
1hr = 60mins
Add the 60mins with 30mins since it’s 1hr and 30 mins. Which will equal 90mins
9miles/ 90minutes
You can simplify
1 mile/ 10 mins
So for 1 mile it takes 10 mins
And the problem is asking how much will it take for her to run 12 miles
Meaning it will take 120 minutes for her to run 12 miles.
The answer is (3) 24/26 because Sin is opposite over the hypotenuse so there's how you get 24 over 26
Is this a relation: {(-2,1), (0,0), (0,1), (1,-2), (1,0), (1,3), (2,0)}? Explain why or why not.

It is a relation because any relation is simply a set of (x,y) values known as points or ordered pairs. There are no other qualifications needed to be a relation. We simply pair up any x and y value we want.
I think you meant to ask if it's a function or not. If so, then the answer is "no, it is not a function". Why not? Because the x value x = 0 produces more than one y output y = 1 and y = -2. Graph these points and you'll see them fail the vertical line test (ie its possible to draw a vertical line through more than one point on the graph). The same issue happens with (1,-2), (1,0) and (1,3) as well.
In summary:
Yes it is a relation
No it is not a function
The reasoning for each is stated above
