Question

please help?
Graph the system of inequalities and list each corner point.
x+13y >= 14
29x+y>=30
y>=0
x>=0
i got the corner points to be (1,1),(14,0),(30/29,0) or (1,1),(0,0),(1.034,0),(0,1.1) but both were wrong?

Answer 1

draw the other line on this graph

Answer 2

how?

Answer 3

how do you draw a line when you have the equation?
1) find out two points (easy to set x=0 and find 'y' and then set y=0 and find 'x')

Answer 4

2) connect the two points and extend it

Answer 5

ya i got (0,30) and (30/29,0) ?

Answer 6

but i dont know where those points are on the graph you made?

Answer 7

good. put the points on the graph and connect them.
when you take your mouse over the "pencil" button oin the diagram, click on it

Answer 8

i did that but how do i know where (0,30) is on that graph?

Answer 9

approximate it. it must be beyond the (14,0) point

Answer 10

the black line? would that be abouts where it is?

Answer 11

great. but since we are simply approximating,
we can have it like this:

Answer 12

now, from inequality we are looking
(1) "above" x+13y=14
(2) "above" 29x+y=30
(3) "above" X-axis (equation of X-axis is y=0)
(4) "Right of" Y-axis (equation of y-axis is x=0)
