Which relation represents f(x) = 2x - 5?
{(0,-5), (1, -3), (2, 1), (3, 1))
{(0,-5), (1,3), (2, -1), (3, 1))
{(0,-5), (1, -3), (2, -1), (3, 1);
{(0,5), (1, -3), (2, -1), (3, 1)}

{(0,-5), (1, -3), (2, -1), (3, 1)

Step-by-step explanation:

If you plug in 1 for x you get f(x)=2(1)-5 which equals 2-5=-3

You would repeat these steps just going up by one number every time

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!
