Need answers and work shown anyone know how to do this

1) C. Because it says the number of years SINCE 2000.

2) The negative integers are -4, -3, -2, -1 because these are the only negative numbers between -5 and 5.

3) Put the point, which should be shaded in on -6 and color the rest of the line to the left because it claims that -6 is LESS THAN or equal to x. Tip: If you have a variable alone on the left side EX: x<5, then you have to shade the way the arrow, or sign is pointing. Remember, this does not include variables with numbers in from of them EX: 3x>8. In this situation, you would have to divide 8 by 3 and then you can work with it.

if gloria has "carry over" minutes, (that is, any minutes paid for but not used in a month can be applied to her payment for minutes in the next month,) her total usage for the three months is: total minutes = 320 + 243 + 489 = 1052 minutes number of 200 minute blocks = 1052/200 = 5 r52 (that is 5 with a remainder of 52) rounding up the number of 200 minute blocks gives her usage for the three months as 6 blocks. the cost for six blocks is 6 x $25 = $150 she also has 200 - 52 or 148 carry over minutes if gloria pays each month and unused minutes are lost, applying the rounding up procedure to each month gives: first month usage of 320 minutes rounds up to 2 blocks of 200 minutes for a payment of 2 x $25 = $50 second month usage of 243 minutes rounds up to 2 blocks of 200 minutes for a payment of 2 x $25 = $50 third month usage of 489 minutes rounds up to 3 blocks of 200 minutes for a payment of 3 x $25 = $75 total payments for the three months are $50 + $50 + $75 = $175 get the plan with carry over minutes!
