Answer:
See attachment
Step-by-step explanation:
We want to graph the following equation:
x-y+1=0
and
3x+2y=12
For the first equation: x-y+1=0
When x=0, we have 0-y+1=0---->y=1
We plot the point (0,1)
When y=0, we have x-0+1=0---->x=-1
We plot (-1,0)
We draw a straight line through these two points to get the graph of this line.
For the second equation: 3x+2y=12
When x=0,y=6. So we plot (0,6)
When y=0, x=4, So we plot (4,0)
We draw another straight line through them to obtain the graph in the attachment.
40 is the answer for the equation 20+20=40
Answer:
$287.82
Step-by-step explanation:
60 * 2.30 = 138
30 * 2.75 = 82.5
34 * 1.98 = 67.32
138 + 82.5 + 67.32 = 287.82
Answer:
-1
Step-by-step explanation:
the additive inverse of -5is5 because (-5+5=0) &
the multiplicative inverse of -5is 1/-5. because (-5*1/-5=1)
therefore 5*1/-5=5/1*1/-5
=5/-5
=-1
