Using the relation f(x) = 2x + 16, what is the value of x if f(x) = 40?

Answers

true or false: to find the second derivative of a function take the derivative of the furst derivative if the function

Answers

Answer:

True

Step-by-step explanation:

The second derivative of an implicit function can be found using sequential differentiation of the initial equation F(x,y)=0. At the first step, we get the first derivative in the form y′=f1(x,y). On the next step, we find the second derivative, which can be expressed in terms of the variables x and y as y′′=f2(x,y).

If you earned $240 interest on a loan of $600 at an interest rate of 5%, how many years was the loan for?

Answers

Answer:

The loan was for 8 years.

Step-by-step explanation:

It is stated that you earned $240 interest on a loan of $600 at an interest rate of 5%.

Find the duration time by using the formula

I = Pit

Here:

'I' is the interest'P' is the total principal loan'i' is the rate of interest per year't' is the total time in years

substituting I = $240, P = $600 and i = 5%

I = Pit

t = I / Pi

 = 240 / (0.05 × 600)

 = 240 / 30

t = 8 years

Therefore, the loan was for 8 years.

Answer:

The common factors for 4,8 are −4,−2,−1,1,2,4 - 4 , - 2 , - 1 , 1 , 2 , 4 .

Step-by-step explanation:

There ya go, mate.

The greatest common factor of the expression 4x + 8 will be 4.

What is the highest common factor?

The Highest Common Factor (HCF) of two numbers is the highest possible number that is divisible by both numbers.

In other words, the highest common factor is the common factor between the two numbers but it should be the highest among all common factors.

As per the given expression,

4x + 8

The highest number that can be take common in the above expression is 4 as,

4(2x + 2)

Thus, 4 will be the GCF.

Hence "The greatest common factor of the expression 4x + 8 will be 4".
