3/4 because 1/2 equals 50% and 1/4 plus that would be 75% less than 6/8
opposites are also called additive inverse and have the sum of zero.
I belive what you have to do is substitute the x with the numver given on the left, so the first one would be -3-13 which is -16, so then that means y= -16 , so the ordered pair would be (-3,-16)
Hope this helps!!
9x17 is greater. I’d say you can tell because 17 is greater than 15 so the product would be greater too
X² + y = 4 and -y³ = 1x -5 are not linear equation because they contain a variable with a exponents. These types of equation are called quadratic equations.
