Answer:
417
Step-by-step explanation:
3(2+1-3)-212*2+1-4=?
3-212*2+1-4=?
3-423+1-4=?
420+1-4=?
421-4=?
417
5 and above give it a shove, 4 and below let it go
So if the number in the tenths spot it 5 and above you round up, if it is 4 and below you take the whole number in the original number used and that is your answer. In this case the tenth spot is 5 so you round it to 90
Answer:
-2.5x-.5

draw the dotted line (3/7)x-3 and shade below it
Step-by-step explanation:
First, we need the slope
Use the slope formula:

so we have
y= -2.5x+b
Solve for b by plugging in coordiantes
-8= -2.5(3)+b
-8= -7.5+b
b= -.5
Put it together and get -2.5x-.5
2.)
A line is parallel to another line if they have the same slope (and different y intercepts)
So in the formula y=mx+b we knowe that m= 2/3
Now it's just a matter of solving for B
plug in the required coordinate to do this
-1=(2/3)*0+b
-1= b
Put it all together to get

3.)
put this into slope intercept form
3x-7y>21
3x-21 > 7y
(3/7)x-3 >y
To graph this just draw a dotted line with the equation (3/7)x-3 and shade everything below it (use de_smos if you're stuck)
Then, the median is found by taking the mean (or average) of the two middle most numbers.
