Which set of values could be from a direct proportion

mr Goodwill [35]

Answer:

First table

Step-by-step explanation:

We have to find the set of value which could be from a direct proportion.

We know that

Direct proportion :

When x is directly proportional to y

$x\propto y$

$x=ky$

Where k=Proportionality constant

$k=\frac{x}{y}$

K remain constant when x and y are in direct proportion

From first table

$k=\frac{\frac{1}{2}}{6}=\frac{1}{12}$

$k=\frac{1}{12}$

$k=\frac{2}{24}=\frac{1}{12}$

$K=\frac{3}{36}=\frac{1}{12}$

When x and y are both varies then ratio of x and y remain constant.Hence, it is in direct proportion.

From second table

$k=\frac{0}{0}=$ not ]define

$k=\frac{1}{1}=1$

It is not direct proportion because k does not remain constant.

From third table

$k=\frac{0}{2}=0$

$k=\frac{2}{4}=\frac{1}{2}$

It is not direct proportion because k does not remain constant.

Find two numbers for which the sum is 101 and the difference is 47

ANEK [815]

Answer:

74 and 27

Step-by-step explanation:

let x and y be the numbers

x + y =101........eqn 1

x - y = 47.......eqn 2

solve simultaneously

from equation 2, make x the subject

x= 47 + y........eqn 3

put eqn 3 into eqn 1

(47+y) + y = 101

47 + 2y = 101

2y= 101 - 47

2y=54

y= 54/2

y= 27

put y=27 into eqn 3

x = 47 + 27

x = 74

Find two values for k such that the trinomial x2 – 7x + k can be factored over the integers. Explain your reasoning.

vova2212 [387]

Answer:

1) For $a = 1$ : $b = 6$ and $k = 6$ , 2) For $a = 3$ : $b = 4$ and $k = 12$

Step-by-step explanation:

The polynomial $y = x^{2} - 7\cdot x + k$ is a second-order polynomial of the form $(x-a)\cdot (x-b) = x^{2}-(a+b)\cdot x + a\cdot b$ . By direct comparison, we construct the following system of equations:

$a + b = 7$ (1)

$a\cdot b = k$ (2)

By (1) we know that there are a family of pairs such that the system of equations is satisfied. Let suppose that both $a$ and $b$ are integers. We assume two arbitrary integers for $a$ :
