Answer:

4/9 and 8/9

Step-by-step explanation:

\frac{2}{3} and \frac{2}{9} you have to have a common denominator so you take 3 and 9 and find what they both go into and that number is 9 so take 2/3 and times the top and bottom by 3 to get 6/9 and 2/9 by 1 to get 2/9 once you have those subtract them to get 4/9 and that's your first answer then take them and add so you get 8/9 which is your second answer.

Which graph shows a system of equations with no solutions?
podryga [215]

Graph of Parallel lines shows a system of equations with no solutions

Step-by-step explanation:

Consider a set of equations

7x - 2y = 16\\21x + 6y =24

If we solve this both equations using any one of the solving method, (Substitution method) then we will get

7x-2y=16\\7x=16+2y\\x=\frac{16+2y}{7}

substituting the following x in 2nd equation (21x + 6y = 24) We get

21(\frac{16+2y}{7} )+6y=24\\3(16+2y)+6y=24\\48+6y+6y=24\\12y=24-48\\y=-\frac{24}{12} \\y=-2

Put y= -2 in x equation

x=\frac{16+2(-2)}{7}\\ x=\frac{16-4}{7}\\\x=\frac{12}{7} \\x=1.71

Comparing these (x,y) values we can understand that they never meet at a point
