WARRIOR [948]3 years ago

Given:-

{log}↓{2} (3x - 1) = 3

We can write it in the exponential form :-

3x - 1 =  {2}^{3}

Solving for <em>x </em>from the above equation, we have-

3x - 1 = 8

→3x = 8 + 1

→3x = 9

→x =  \frac{9}{3}

→x = 3

Therefore, value of x is <u>3</u>

If h(x) = (f o g)(x) and h(x) = ∛7x+1, find f(x) and g(x)
Mariana [72]
There's more than one way to combine them really
but an obvious one will be

\bf \begin{array}{llll}&#10;h(x)&=&(f\circ g)(x)\\\\&#10;&&\sqrt[3]{7x+1}\\\\&#10;&&\sqrt[3]{g(x)}\leftarrow &#10;\begin{array}{llll}&#10;f(x)=\sqrt[3]{x }\\\\&#10;g(x)=7x+1&#10;\end{array}&#10;\end{array}\\\\&#10;-----------------------------\\\\&#10;(f\circ g)(x)\iff f[\quad g(x)\quad ]=\sqrt[3]{g(x)}\implies  f[\quad g(x)\quad ]=\sqrt[3]{7x+1}

Which statements about the factors of the terms in the expression 20 a + 15 a b + 24 b are true? Select three options.
ExtremeBDS [4]

Answer:

Following are the true statements

2. The factors common to 20a and 15ab are 1, 5, and a.

3. The factors common to 20a and 24b are 1, 2, and 4.

5. The GCF of the expression is 1

Step-by-step explanation:

Expression is  20a + 15ab + 24b

Now lets have a look at each of the options provided!

1. The factors common to 20a and 15ab are 1, 5, a, and b.

False

As you can see there is no b in 20a term only 1,5,a are common hence it is false.

2. The factors common to 20a and 15ab are 1, 5, and a.

True

The terms 20a and 15ab are divisible by 1,5,a hence it is true.

3. The factors common to 20a and 24b are 1, 2, and 4.

True

The terms 20a and 24b are divisible by 1,2,4 hence it is true

4. The GCF of the expression is ab.

False

20a + 15ab + 24b

As you can see ab is not common in all of the terms hence it cannot be greatest common factor

5. The GCF of the expression is 1

True

Factor of 20 are: 2,2,5,1

Factor of 15 are: 3,5,1

Factor of 24 are: 2,2,2,3,1

As you can see the only common factor among all the terms is 1 hence GCF is 1.

In 1990, a person is 15 years old.
Evgesh-ka [11]

Answer:

Well, if this were to be BC= Before Christ, the years would go back.

Step-by-step explanation:

And that's why the question is trying to trick you. So in 1990 BC the person is 15 years old. 5 years later, the same person is now 10 years. 5 years back is the order of the BC concept. Hope this makes sense!
