Is (-6,7) a solution to this system of inequalities?
y> -x + 1
y > 1/3x -9

y>-x+1

7>-x(6)+1

7>6x+1

6>6x

1>x

y>1/3x-9

7>1/3x(-6)-9

7>-2x-9

16>-2x

8>x

Both of these equations are true which means this coordinate point is a solution to this set of equations.

Hope this helps!  :)

Step-by-step explanation:

c - they will have the same distribution

step-by-step explanation:

this is the only one that could make sense. : )

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!
