The value of y varies directly with the value of x, and y = –21 when x = 3.Which equations represent the relationship between y and x?
Choose exactly two answers that are correct.
Answers
it is represented by
y/x=k where k stay the same
so y=-21
x=3
the equation is -21/3=-7
k=-7
so k =-7
therfor
y/x=-7
then manipulate the equation
multiply boht sides by x
y=-7x
subsitute valuse for x and get values for y
if (x,y)
(1,-7)
(2,-14)
(3,-21)
so posiible equationscould be
-7/1=-7
-14/2=-7
-21/3=-7
and so on
Answer:
X=17
Y=62

The given expression are just three examples of the many possiblecombinations that can add up to 800.
To find three different ways in which two numbers can be added to equal 800, we can explore different combinations. Here are three examples:
1. Combination 1:
600 + 200 = 800
In this combination, the numbers 600 and 200 are added together to equal 800.
2. Combination 2:
400 + 400 = 800
In this combination, the numbers 400 and 400 are added together to equal 800.
3. Combination 3:
350 + 450 = 800
In this combination, the numbers 350 and 450 are added together to equal 800.
The key is to find two numbers whose sum equals 800. You can experiment with different pairs of numbers and add them together to find other valid combinations.

Here are some:
800 + 0 = 800
700 + 100 = 800
600 + 200 = 800
500 + 300 = 800
400 + 400 = 800
799 + 1 = 800
798 + 2 = 800
And so on.

20/2 = r + 7
10 = r + 7
10 - 7 = r
3 = r
r = 3
The answer is: r = 3.

closed means 'up to and including'
example
x>3 would have open dot, meaning greater than 3, you can get close to 3, but not 3 like x=3.00000000000000000000001 is a solution, but you cant get to x=3
x>3 would be closed, this would include 3 and up so x=3 is a solution, als x=4, but not less than 3
