The difference y less than 10

The difference is : 10 - y

Step-by-step explanation:

Let we donate the required difference by 'd'

Now, we need to find difference(d) in such a way that it is y units less than 10. So, Using concept of algebraic expressions :

A number which is less than another can be found by subtracting first number from the second number :

So, the required difference is given by : d = 10 - y

easy its decreasing

step-by-step explanation:

because its top point is at the to of the graph on the left side (atleast from the veiw i see it) now if that top point wast in the lower part of the graph it would be increasing hope this have a nice day
