Anumber less 7 is greater than -45. how can the solutions for this inequality be described? is -40 a solution?

All numbers greater than -38.; no

Step-by-step explanation:

Any value of x that is greater than -38 will satisfy the inequality. However, -40 is not greater than -38.

I hope this helps :) :)

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
