Given a set of values
{(2,7). (8, 12). (5,9). (10.15)),
determine which numbers do not
belong in the following examples.
Why?
Explain in your own words.
Domain: (2,5, 7, 8, 10)
Range: (7.9. 10. 12. 15)

Answers

Try to determine the value when they all add up. Or If you’re working with fractions try cross canceling

Step-by-step explanation:

given : (2,7). (8, 12). (5,9). (10.15)

domain: will always be the first value of numbers ; 2, 8, 5, 10

range: will always be the second value of numbers ; 7, 12, 9, 15

what you have here is :

Domain: (2,5, 7, 8, 10)

Range: (7.9. 10. 12. 15)

what's wrong is 7 is in the domain, and 10 is in the range. those two don't belong there. theres also a extra number you have in there. domain and range should only have 4 numbers. since there is four pairs/set of values

I will give Brainly! Pls, help!

Answers

Answer: -54+17 is less

Step-by-step explanation:

This is true because a positive number + a negative number is like subtracting a number. 35+(-61) or 35-61= -26 and -54+17=-37.

ok, let's go
-54 + 17 = [original]
17-54 = [move numbers to make easier to read]
17-54 = -37 [simplify]

35 + (-61) = [original]
35 - 61 = [adding a negative is the same as subtracting a positive]
35 - 61 = -26 [simplify

-37 is smaller than -26

ANSWER
-54 + 17 is less
