Answer is choice C) Inverse property of addition; a number and its inverse are added

The number is 0.3 and its additive inverse is -0.3, which add to 0. You can flip things around to say that the number is -0.3 and its additive inverse is 0.3 to add them to the same result of 0. The order of addition doesn't matter. It's like saying 2+3 = 5 and 3+2 = 5

Subtract 7x^2−5xy+8y^2 from −2x^2−15xy+9y^2
Ghella [55]

Answer:

y^2-10xy-9x^2

Step-by-step explanation:

We want to subtract 7x^2 -5xy+8y^2 from -2x^2-15xy+9y^2.


We set up the subtraction problem as follows:


(-2x^2-15xy+9y^2)-(7x^2-5xy+8y^2).


We expand the brackets to obtain;


=-2x^2-15xy+9y^2-7x^2+5xy-8y^2.


We regroup the terms to obtain;


=9y^2-8y^2-15xy+5xy-2x^2-7x^2.


We now simplify to obtain;


=y^2-10xy-9x^2.
