Answer:
x=-1, y=3
Step-by-step explanation:
3x+2y=3
3x-2y=-9
since we have -2y and 2y we can just add the equations
6x=-6
x+0y=-1
x=-1
to solve x using elimination multiply the top equation by -1
-3x-2y= -3
3x-2y=-9
and add
0x-4y=-12
-4y=-12
y=3
and substitute x and y to double; check
3(-1)+2(3)=3
-3+6=3
3=3
checks out so these are correct
It is easy to go to tiger math and type that in
I think you'r right but I cant see the quitction
The picture cannot be dilated to fit the frame. This is because one side of the picture is already 6-inches. So, therefore you cannot dilate the picture to fit the frame.
Answer:
$104.70
Step-by-step explanation:
The equation would be set up like this: 80.45 + 20.50(3) - 37.25. You started off with $80.45 in your bank account and deposited, or added, $20.50 every day on Tuesday, Wednesday and Thursday. That would mean you added $20.50 three times. Adding $80.45 + $20.50 + $20.50 + $20.50, simplified to $80.45 + $20.50(3) would get you $141.95 in total. Then, on Friday, you withdraw $37.25, getting the equation $141.95 - $37.25, leaving $104.70 for the weekend.
