Which ordered pairs make both inequalities true? check all that apply. (−5, 5) (0, 3) (0, −2) (1, 1) (3, −4)

(0, -2) and (1, 1) both work in this system of equations. 

The best way to find if it is a solution is to look for those points on the graph. When you graph the point, it needs to fall in an area where both lines or shaded or on a solid line. 

(0, -2) falls on a solid line. 

(1, 1) falls in the double shaded area. 

the law of definite proportions states samples of a compound will always contain the same proportion of elements by mass. in other words, a given compound will always contain the same elements in the same proportions by mass.the law of multiple proportions states when two elements combine with each other to form more than one compound, then the weights of one element that combine with a fixed weight of the other are in a ratio of small whole numbers.
