Answer:
A constant
Step-by-step explanation:
Well, ideally I'd like more details, but a number that doesn't change in a mathematical equation is called a constant.
2×+y=0,
×-y=6
Add the 1st to the 2nd equation==> 3x +y-y=6+0==> 3x=6 & x=2
Plug 2 into any of the equation & you will get y=-4
10 think about it it’s 60s and it’s in the ten’s place because 10,20,30,40,50, and 60
Answer:
13 means the starting number
13 is the y-intercept (0,13)
For this case we have the following inequality:

To solve we have:
Subtracting 6 from both sides of the equation:

Thus, the solution is given by all values of r greater than or equal to 5.
Answer:
The solution is given by all values of r greater than or equal to 5.
