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.

Find x. Give reasons to justify your solution. b Lines AB and CD are straight lines.

MArishka [77]

Answer:

x = 28

Step-by-step explanation:

Given that lines AB and CD are straight lines that intersects at O, it follows that the pair of opposite vertical angles formed are congruent.

Thus,

<AOD = <BOC

<AOD = 152°

<BOC = 3x + x + (x + 12) (angle addition postulate)

<BOC = 5x + 12

Since <AOD = <BOC, therefore,

152° = 5x + 12 (substitution)

152 - 12 = 5x (subtraction property of equality)

140 = 5x

140/5 = x (division property of equality)

28 = x

x = 28

Find the missing side lengths. Leave your answers as radicals in simplest form.

Citrus2011 [14]

This is the isosceles right triangle, the diagonal of a square, the thing that so upset the Pythagoreans. The two sides and diagonal of a square are in ratio $1:1:\sqrt{2}$ so we get

$u = v = 8$

We could have also gotten this using Trig:

$u = (8 \sqrt{2}) \sin 45^\circ = 8 \sqrt{2}/\sqrt{2} = 8$

$v = (8\sqrt{2})\cos 45^\circ = 8$

Or by recognizing u=v because remaining angle is 45 so this must be isosceles so

$u^2 + u^2 = (8 \sqrt{2})^2$

$2u^2 = 2 (8^2)$

$u = 8$

(-4,1) and (-8,7) <br><br> write an equation in slope-intercept form

Alchen [17]

Answer:

y = -2x - 9

Step-by-step explanation:

so we have our two points, (-4,-1) and (-8,7) What we need to do to find our slope is y2 - y1 over x2 - x1. Once plugging in the numbers and subtracting it should give you 8/-4. 8 divided by -4 is -2. m = -2. Now to find our "b" we plug in our slope, and plug in one of the two points into the format of y = mx + b.

-1 = -2(-4) + b

multiply -2 and -4

-1 = 8 + b

we subtract 8 from itself and -1

-9 = b

Our equation is y = -2x - 9
