If the equation is n+4/2-3=13 than 'n' will be 28 but how would you get the answer 14?

Answers

Answer 1

Answer: There's only one number that 'n' can be.
It's called the solution to the equation.

You said n + 4/2 - 3 = 13

Notice that 4/2 is really 2 : n +   2    - 3 = 13

Notice that 2 - 3 = -1    n    - 1    = 13

Add 1 to each side:    n    = 14 .

That's the solution. 'n' is 14 . It's not 28 .

What is the standard form of 0.002?

Answers

Answer:

Standard form $2 * 10^(-3)$ .

Step-by-step explanation:

Given : 0.002

To find : What is the standard form.

Solution : We have given 0.002

To convert it in to standard form

Remove decimal

0.002 = $(2)/(1000)$ .

By exponent rule

$(1)/(1000) = 10^(-3)$ .

Then ,

$(2)/(1000)$ = $2 * 10^(-3)$ .

Therefore, Standard form $2 * 10^(-3)$ .

0.002 in standard form is:

2 x 10-3

The set of ordered pairs shown represents a function, f,{(–5, 3), (4, 9), (3, –2), (0, 6)}

Select THREE ordered pairs that could be added to the set that would allow f to remain a function.

Question 10 options:

A)

(-3, -2)

B)

(4, 0)

C)

(0, -1)

D)

(1, 6)

E)

(2, 3)

F)

(-5, 9)

Answers

Answer:

B) (4, 0)

C) (0, -1)

E) (2, 3)

Step-by-step explanation:

If we see the rule of function then it says that,

a function is a special relationship where each input, x, has a single output, y.

It means that for every value of x there SHOULD be a different value of y.

(-3,-2) Rejected

because when x = 3, y = -2

(1, 6) Rejected

because when x = 0, y = 6

(-5, 9) Rejected

because when x = 4, y = 9

Answer:

The correct options are A, D and E.

Step-by-step explanation:

The given set of ordered pairs represents a function

$f=\{(-5, 3), (4, 9), (3, -2), (0, 6)\}$

We need to find THREE ordered pairs that could be added to the set that would allow f to remain a function.

A relation is a function if there exist unique value of y for each value of x.

The x values for given function are -5, 4, 3 and 0.

If we add (-3,-2) in the given set, then we unique value of y for each value of x. So, option A is correct.

If we add (4,0) in the given set, then we have y=0 and y=9 at x=4. Since the set have more than one value of y for same x-value, therefore option B is incorrect.

If we add (0,-1) in the given set, then we have y=-1 and y=6 at x=0. Since the set have more than one value of y for same x-value, therefore option C is incorrect.

If we add (1,6) in the given set, then we unique value of y for each value of x. So, option D is correct.

If we add (2,3) in the given set, then we unique value of y for each value of x. So, option E is correct.

If we add (-5,9) in the given set, then we have y=9 and y=3 at x=-5. Since the set have more than one value of y for same x-value, therefore option F is incorrect.

Therefore the correct options are A, D and E.

Explain how am estimate helps you to place the decimal point when multipling 3.7 X 5.1

Answers

well 3.7×5.1 put the decimals at the end so 37×51=1887 there is 2 decimals so it should be 18.87 you put it back 2 spaces since there's 2 decimals

Since 3*5=15, then the answer to 3.7*5.1 should be close to that same value. But if you were solving it by hand, and accidentally wrote the answer as 1.887 or 188.7. Estimating helps you know that you placed the decimal in the wrong area, Since the number isn't close to 15.3.7*5.1+18.87
