the sum of two numbers is 9. if one number is subtracted from the other, the result is 3. find the numbers

Answers

Answer 1

Answer: x, y - the numbers

The sum of the two numbers is 9.
$x+y=9$

If one number is subtracted from the other, the result is 3.
$x-y=3$

Solve the system of equations:
$x+y=9 \n\underline{x-y=3} \nx+x=9+3 \n2x=12 \ \ \ |/ 2 \nx=6 \n \nx+y=9 \n6+y=9 \ \ \ |-6 \ny=3$

The numbers are 6 and 3.

Answer 2

Answer: Let's say x to the first number and y to the second one.
We add them : $x+y=9$
Then we substract them : $x-y=3$
Now we add the equations:

$(x+y)+(x-y)=9+3\n x+x+y-y=12\n 2x=12\n \n x=\frac { 12 }{ 2 } \n \n x=6$

and finally rewrite the equation:

$6+y=9\n y=9-6\n y=3\n \n x=6\quad and\quad y=3$

Variable p is 2 more than variable d. Variable p is also 1 less than variable d. Which pair of equations best models the relationship between p and d? p = d + 2
p = d – 1
p = d – 2
p = d + 1
d = 2p
d = 2p – 1
d = 2p
d = 2p + 1

Answers

If you would like to find a pair of equations that best models the relationship between p and d, you can do this using the following steps:

p is 2 more than d ... p = d + 2
p is 1 less than d ... p = d - 1

The correct result would be p = d + 2 and p = d - 1.

The pair of equations that models the relationship between p and d are expressed as: p = d + 2, and p = d - 1.

What is an Equation?

An equation is used to represent a situation using variables (letters) and figures.

"p is 2 more than d" can be expressed as: p = d + 2.

Also, we can represent the statement, "p is 1 less than d" as: p = d - 1.

Therefore, the pair of equations would be: p = d + 2, and p = d - 1.

According to the Rational Root Theorem, which could be a factor of the polynomial f(x) = 60x4 + 86x3 – 46x2 – 43x + 8?x – 6
5x – 8
6x – 1
8x + 5

Answers

the answer is (6x-1)

Answer: The answer is (B) $(8)/(5)$ and (C) $(1)/(6)$ .

Step-by-step explanation: The given polynomial is

$f(x)=60x^4+86x^3-46x^2-43x+8.$

We are to select the correct option that could be a factor of the polynomial f(x) according to the Rational Root Theorem.

The Rational Root Theorem states that:

If the polynomial $P(x)= a_nx^n+a_(n-1)x^(n-1)+\cdots+a_2x^2+a_1x+a_0$ has any rational roots, then they must be of the form $\pm\frac{\textup{factors of }a_0}{\textup{factors of }a_n}.$

Factors of 60 are 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60 and factors of 8 are 1, 2, 4 and 8.

Out of the given options, only $(8)/(5)$ and $(1)/(6)$ can be written in the form $\pm\frac{\textup{factors of }a_0}{\textup{factors of }a_n}.$ , because

$(8)/(5)=\frac{\textup{a factor of 8}}{\textup{a factor of 60}},\n\n(1)/(6)=\frac{\textup{a factor of 8}}{\textup{a factor of 60}}.$

Thus, (B) and (C) are the correct options.
