That would be 3'000 + 4000 + 400 + 80 = 7,480
33 would be 30 and 89 would be 90
1. True: the absolute value works exactly in this way: it turns negative numbers into their positive counterpart (e.g.: |-3|=3), and it does nothing on positive numbers (e.g.: |10|=10). So, the absolute value of a negative number will always be a positive number.
2. True (see above)
3. False: for example, you can pick -100 and 30. Their absolute value is 100 and 30, and 100>30. So, the absolute value of a negative number is greater the absolute value of a positive number.
You are told that y=-5, so just use that value for y in the second equation...
5x+4(-5)=-20
5x-20=-20
5x=0
x=0 so the solution, when the lines intersect, is the point (0,-5)
