Answer:

Step-by-step explanation:

Let's first convert this to numbers. When a number is decreased by a certain amount, that is the same as saying that something is subtracted from it. Therefore:

a-7=2

Add 7 to both sides:

a-7+7=2+7

a=9

Hope this helps!

Answer:

Step-by-step explanation:

If a number (Let's call it x) has been subtracted by 7 (x - 7) then to find the previous number you just do the opposite. Let's call the end result y. 2 + 7 = x (Or y + 7 = x). <u>2 + 7 = 9.</u>

What is the derivative of e^(2x)

KIM [24]

Using the chain rule: The derivative of e^u is (e^u)(u'). Notice that e^u is rewritten exactly as is and then multiplied by the derivative of the exponent.
Let u=2x. So u'=2
So the derivative of e^u is e^(2x)*2 This can also be written as 2e^(2x).

Division A reports the following data: Sales = $180,000, Net income = $18,000, Average'assets

Karolina [17]

Company A is operating more efficiently

Step-by-step explanation:

Given parameters:

Division A:

Sales = $180,000

Net income = $18,000

Average assets = $72,000

Division B:

Sales = $60,000

Net income = $9,600

Average assets = $48,000

Unknown:

Division operating more efficiently = ?

Solution:

Efficiency measures the relationship between the output from a business and the input into it. Here, the efficiency is the relationship between the net income and the average assets. it can be expressed as a percentage or ratio.

The net income is the profit derived from sales of a company's products.

The higher the value the more efficient a company is.

Efficiency = $\frac{net income}{Average assets}$ x 100

Efficiency of division A = $\frac{18000}{72000}$ x 100 = 25%

Efficiency of division B = $\frac{9600}{48000}$ x 100 = 20%

Division A has a higher efficiency compared to B
