Is it possible for a number to be a rational number that is not an integer but is a whole number? Explain.

1 answer:

4 0

No because every integer is a rational number, since each integer can be written in the form x/1. For example 12 = 12/1 and thus 12 is a rational number. And also every whole number is a rational number: for example, 12= 12/1. So it is rational.

4/5 x (v−7) = 2 what is the value of v

Juliette [100K]

Answer:

4/5x(v-7)=2

multiply both sides by 5/4, the reciprocal of 4/5

v-7=2x(5/4)

Express 2x(5/4) as a single fraction

v-7=2x5

Multiply 2 and 5

v-7=10

Reduce the fraction 10/4 to the lowest by extracting and cancelling 2

v-7=5

Add 7 to both sides

v=5+7

Covert fraction to 14/2

v=5/2+14/2

Since 5/2 and 14/2 have the same denominator, add them by adding their numerators

v=5+14

Add 5 and 14 together

v=19

2. Graph the inverse of the function, then determine if the inverse is a function.

charle [14.2K]

The inverse of the function f(x)= x^2 is a function.

<h3>The graph of the inverse</h3>

The equation of the function is

f(x)= x^2

Rewrite as:

y = x^2

Swap x and y

x = y^2

Make y the subject

$y = \sqrt x$

Rewrite as:

$f^{-1}(x) = \sqrt x$

So, the inverse of f(x)= x^2 is $f^{-1}(x) = \sqrt x$

See attachment for the graph

<h3>Is the inverse a function?</h3>

The inverse is a function.

This is so because it passes the vertical line test

The first two terms of an arithmetic sequence are 7 and 4. Find the 7th term.

kobusy [5.1K]

EXPLANATION

If the first two terms of an arithmetic sequence are 7 and 4, then we know that an arithmetic sequence has a constant difference d and is defined by

$a_n=a_1+(n+1)d$

Check wheter the difference is constant:

Compute the differences of all the adjacent terms:

$d=a_{n+1}-a_n$

Replacing terms:

4-7 = -3

The difference between all of the adjacent terms is the same and equal to

d = -3

The first element of the sequence is

$a_1=7$ $a_n=a_1+(n+1)d$

Therefore, the nth term is computed by

d= -3

$a_n=7+\text{ (n-1)}\cdot(-3)$

Refine

d= -3 ,

$a_n=-3n+10$

Now, replacing n=7

$a_7=-3\cdot7+10\text{ = -11}$

So, the answer is -11.
