2. Is the point ( -5,11) a solution to the following system of equations? Show your work.
y = -x + 6
y=-3x – 4

Yes it is

Step-by-step explanation:

y = -x + 6

y = -3x - 4

(-5,11)

x = -5

y = 11

y = -x + 6

(11) = -(-5) + 6

11 = 5 + 6

11 = 11

y = -3x - 4

(11) = -3(-5) - 4

11 = 15 - 4

11 = 11

the answer is d. 75%

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!
