which of the following statements shows the inverse property of addition?

a. y + (-y) = 0
b. y + 0 = y
c.1y = y
d. y + y = 2y

by definition, an arc subtended by a central angle of some given measure has the same measure. so .

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
