What is the excluded value?a/b-2

1. a=0
2. b=2
3. b=-2
4. none of the above

Answers

Answer 1
Answer:

Answer:  The correct option is (2) b=2.

Step-by-step explanation: We are given to find the exclude value for the following algebraic expression:

E=(a)/(b-2)~~~~~~~~~~~~~~~~~~~~~~(i)

We know that

for a rational expression, we must exclude those values for which the denominator of the fraction becomes zero.

So, in equation (i), the excluded value will be given by

b-2=0\n\n\Rightarrow b=2.

Thus, the required excluded value is b=2.

Option (2) is CORRECT.
Answer 2
Answer: b - 2 = 0 since you cannot divide by 0
b = 2 solve for b. this is where the function is undefined

Please solve 5x - 1/4 = 3x - 5/4

Answers

subtract 3x from 5x getting 2x so your new equation is: 2x-1/4=-5/4 then you add 1/4 to -5/4 getting : 2x=-1 the you divide both sides by 2 so x=-1/2
5x - 1/4 = 3x - 5/4 
 5x - 3x 
    2x - 1/4 = -5/4
      2x = -5/4 + 1/4 
       2x = -1 
       2x/2 = -1/2 
        x = -1/2 

Peyton has a goal to walk 10,000 steps each day. On Tuesday afternoon,Peyton walked 7,338 steps. She averages 2.5 feet per step

Answers

Please consider the complete question.

Peyton has a goal to walk 10,000 steps each day. On Tuesday afternoon, Peyton walked  7,338 steps. She averages 2.5 feet per step.

How many more feet does Peyton need to walk to reach her goal of 10,000 steps?

First of all we will find the steps Peyton needs to walk to reach her goal.

\text{Steps Peyton needs to walk}=10000-7338

\text{Steps Peyton needs to walk}=2662

Since Peyton averages 2.5 feet per step, so to find number of feet in 2662 steps, we will multiply 2662 by 2.5 as:

\text{Distance that Peyton needs to walk to reach her goal}=2662* 2.5\text{ ft}

\text{Distance that Peyton needs to walk to reach her goal}=6655\text{ ft}

Therefore, Peyton needs to walk 6655 feet to reach her goal.

Explane how you can tell 4 is a factor of 30

Answers

That is very difficult, since 4 is not a factor of 30. The prime factorization of 30 is 2*3*5. There is no combination of these numbers that results in 4, so it is not a factor of 30. 
Just count. 4 8 12 16 20 24 28 32 oop we past 30 so 4 is not a factor of 30.
