Answer:
Part 1) Subtraction Property of Equality
Part 2) This property can be used , because addition and subtraction have inverse relationships
Step-by-step explanation:
we know that
The<u><em> subtraction property of equality</em></u> tells us that if we subtract from one side of an equation, we also must subtract from the other side of the equation to keep the equation the same
so
we have
Solve for y
Applying Subtraction Property of Equality
subtract 10.50 both sides
Remember that this property can be used , because addition and subtraction have inverse relationships.

Answer:
who is nathan
Step-by-step explanation:
do u know her
This is not a function because we have an A with many B. It is like saying f (x) = 2 or 4 It fails the "Vertical Line Test" and so is not a function. But is still a valid relationship, so don't get angry with it. It CAN (possibly) have a B with many A. For example sine, cosine, etc are like that. Perfectly valid functions.
Graph A is the correct answer
