Step-by-step explanation:`

inequalitites are like the functions but sometime they just dont work out when we have squares and their roots and their parabalas and their roots

Which of these lines could possibly intersect the graph of a function at more than one point? Select three that apply.

Vera_Pavlovna [14]

According to Vertical Line test, a vertical line only intersect the graph of a function at one point. Among the choices given, x = 4 is a vertical line. So this line cannot intersect the graph of a function at more than one point. The other three would apply. So the answer choices are A, C and D.

If r and s are positive integers, is \small \frac{r}{s} an integer? (1) Every factor of s is also a factor of r. (2) Every prime

Yuri [45]

Answer:

<em>If statement(1) holds true, it is correct that </em> $\small \frac{r}{s}$ <em> is an integer.</em>

<em>If statement(2) holds true, it is not necessarily correct that </em> $\small \frac{r}{s}$ <em> is an integer.</em>

<em></em>

Step-by-step explanation:

Given two positive integers $r$ and $s$ .

To check whether $\small \frac{r}{s}$ is an integer:

Condition (1):

Every factor of $s$ is also a factor of $r$ .

$r \geq s$

Let us consider an example:

$s = 5^2 \cdot 2\\r = 5^3 \cdot 2^2$

$\dfrac{r}{s} = \dfrac{5^3\cdot2^2}{5^2\cdot2} = 10$

which is an integer.

Actually, in this situation $s$ is a factor of $r$ .

Condition 2:

Every prime factor of <em>s</em> is also a prime factor of <em>r</em>.

(But the powers of prime factors need not be equal as we are not given the conditions related to powers of prime factors.)

Let

$r = 2^2\cdot 5\\s =2^4\cdot 5$

$\dfrac{r}{s} = \dfrac{2^3\cdot5}{2^4\cdot5} = \dfrac{1}{2}$

which is not an integer.

So, the answer is:

<em>If statement(1) holds true, it is correct that </em> $\small \frac{r}{s}$ <em> is an integer.</em>

<em>If statement(2) holds true, it is not necessarily correct that </em> $\small \frac{r}{s}$ <em> is an integer.</em>
