Which of the following expressions is incorrect?

a) sales revenue - cost of goods sold - operating expenses = net income
b) gross profit - operating expenses = net income
c) net income + operating expenses = gross profit
d) operating expenses - cost of goods sold = gross profit

d) Operating expenses - Cost of goods sold = Gross profit

Step-by-step explanation:

first of all when you say gross in accounting it means the totality so gross profit would never be a subtraction.

And finally operating expenses usually go with a negative sign {-} because it means costs or something goes opposite to the revenue of the firm.

d) Operating expenses - Cost of goods sold = Gross profit

Step-by-step explanation:

The formula of Net income is

Sales revenue

- cost of goods sold

= Gross profit

-  Operating expenses

= Net income

So,  we are going to analyze each option

a) Sales revenue - cost of goods sold - Operating expenses = Net income  CORRECT

b) Gross profit - Operating expenses = Net income  CORRECT

c) Net income + Operating expenses = Gross profit  CORRECT

d) Operating expenses - Cost of goods sold = Gross profit INCORRECT

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.
