Which ordered pair (x, y) satisfies the system of equations?

x = y − 3
x/2 + 2y = 6

A) (−3, 0)

B) (0, 3)

C) (6, −3)

D) (36, −6)

(0,3)

Step-by-step explanation:

Plug in the coordinates:

-3=0-3         -3=-3 Right

-3/2+2(0)=6   -1.5=6 Wrong

0=3-3 0=0 Right

0/2+2(3)=6   6=6   Right

6=-3-3 6=-6 Wrong

6/2+2(-3)=6    3+-6=6      3=6 Wrong

36=-6-3  36=-9 Wrong

36/2+2(-6)=6    18-12=6   6= 6 Right

Both have to say right

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!
