Given inequality is
Now we need to find the graph of .
Which can be done into two parts:
First graph the line then shade the graph for inequality sign
Graph the line
we can plug any number for x say x=0 to find the y-value
4x-8y=9
4*0-8y=9
0-8y=9
-8y=9
y=-1.125
Hence first point is (0,-1.125)
Similarly we can plug y=0 then solve for x
4x-8y=9
4x-8*0=9
4x-0=9
4x=9
x=2.25
hence 2nd point is at (2.25,0)
Now graph both points and join them by a straight line.
Since used inequality is so we use solid line not the dotted line.
Shading the graph:
we can pick any test point which is not on the line 4x-8y=9 say (0,0) then plug into original problem to see if that point satisfies the original problem or not.
Which is TRUE.
TRUE means shade in direction of test point otherwise we graph in opposite direction of test point.
Now final graph will look like the graph attached below:
Answer:
(7,10)
Step-by-step explanation:
Since both equations are equal to y, we can set them equal
y=x+3
y=2x-4
x+3 = 2x-4
Subtract x from each side
x+3-x =2x-4-x
3 = x-4
Add 4 to each side
3+4 =x-4+4
7 =x
Now we need to find y
y = x+3
y =7+3

Answer:
He losses 27 $
Step-by-step explanation:
On Monday he got 47$
On Tuesday he loss 12$
On Wednesday he loss 8$
Total :
47 - (12 + 8)
47 - 20 = 27

get their LCD, like you'd with any other fractions, and add them up
Cost divided by number of items equals each items cost
20/16= 1.25
$1.25
