Rogers Company reported net income of $35,000 for the year. During the year, accounts receivable increased by $7,000, accounts p
storchak [24]

Answer:

correct answer is  option C.

Step-by-step explanation:

net income of a year =  $35,000

accounts receivable is increased (AR)= $7,000

accounts payable decrease(AP) = $3,000

depreciation expense = $8,000

net cash provided = net income - increase in current asset (AR) - decrease in  current asset (AP) +non cash flow

net cash provided =  $35,000 -$7,000-$3,000+ $8,000

                               = $33000

hence the correct answer is  option C.

X + 2y = 10
Crazy boy [7]

Answer:

(-12,11)

Step-by-step explanation:

x + 2y = 10

3x + 4y = 8

(-2)x + (-2)2y = (-2)10

3x    + 4y       = 8

-2x - 4y = -20

3x  + 4y = 8

Add to eliminate:

x = -12

Substitute x to solve y:

x + 2y = 10

(-12) + 2y = 10

-12 + 2y = 10

2y = 10 + 12

2y = 22

y = 22 ÷ 2

y = 11

Check:

x + 2y = 10

(-12) + 2(11) = 10

-12 + 22 = 10

10 = 10
