x + y = -2
x + 5y = 2
Ordered pair (-3, 1) ==> x = -3, y = 1
For the fisrt equation:
x + y = -2
-3 + 1 = -2
-2 = -2 True
For the second equation:
x + 5y = 2
-3 + 5(1) = 2
-3 + 5 = 2
2 = 2 True
Answer:
Yes, the ordered pair is a solution because it satisfies both equations
Answer: You do not because the tv costs $464.
Step-by-step explanation:
First find out how much 20% of 580 is:
= 20% * 580
= $116
The television was therefore marked down by $116. The current selling price is:
= 580 - 116
= $464
<em>Since you came with $450, you will not be able to buy the television as you would be short of the $464 required. </em>
The sine of 30 degrees here equals opp / hyp, or (6 m) / g
Then: 1/2 = (6 m) / g
Interchanging g and (1/2), we get g = (6 m) / (1/2) = 12 (meters) (answer)

pls give me a brainly's and I hope this answer can help you
1.
The description of set K as <span> {(x, y) | x - y = 5}, means the following:
the elements of set K are pairs (x,y)
such that: x-y=5, that is we can write(x, y) = (x, x-5).
2.
A set of (ordered) pairs is a function, if each of the first coordinates is paired to only 1 specific value, not 2 or more.
for example: {(1,2), (3, 5), (3, 8)} is not a function because 3 is not paired to only one second value, we have (3, 5) but also (3, 8).
whereas, {(-2, 4), (3, 5), (8.1, 17)} is a function, because each first coordinate is unique, we don't see it again in another pair.
3.
Back in our set K, the description of pairs (x,y) as </span>(x, x-5)
makes sure that each x, produces a specific y, for example in K we have:
(5, 0), and we cannot have (5, a value ≠0), because it would not fit the description (x, x-5)
Answer: yes
