Answer:
Graphing Systems of Linear Inequalities
To graph a linear inequality in two variables (say, x and y ), first get y alone on one side. ...
If the inequality is strict ( < or > ), graph a dashed line. ...
Finally, pick one point that is not on either line ( (0,0) is usually the easiest) and decide whether these coordinates satisfy the inequality or not.
So 1 mol of water in 18 grams of water
so 6.02 times 10^23=18 grams
divide by 18
one way is (6.02/18) times 10^23=0.33444 times 10^23
scientific notation is number more than 1 but less that 10 so
0.33444 times 10=3.344
so take 1 ten from the 10^23 to make 10^22 so
2 sig figs which are non zero numbers
3.3 times 10^22
In second equation add 0.74 and y to both sides: 3.25x+0.74=y;
Substitute y in the first equation: -4.5x-2(3.25x+0.74)=-12.5;
Distribute multiplication over addition:
-4.5x-6.50x -1.48=-12.5;
Combine like terms and add 1.48 to both sides:
-11x= -12.5+1.48;
-11x= 11.02 divide both sides by -11;
X= -11.02/11= -1.00(18)
Y= 3.25• -1.00(18)+.74= -2.515(90)
