In a direct variation, y=10 when x=5. write a direct variation equation that shows the relationship between x and y. write your answer as an equation with y first, followed by an equals sign.

y = 2x

Step-by-step explanation:

Since y varies directly with x, the equation relating them us

y = kx ← k is the constant of variation

To find k use the condition y = 10 when x = 5

k = = = 2

y = 2x ← direct variation equation

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
