Find 2 positive real numbers that differ by 1 and have a product of 1

Mathematics

A) x -y =1
B) x * y =1
B) y = 1/x

A) x -(1/x) = 1
Multiplying both sides by "x"
A) x^2 -1 = x
A) x^2 -x -1 = 0

Solving by the quadratic formula
x = 1.618 and
y = .618

Interestingly, the number 1.6180339... is called the "phi ratio" or the "golden ratio".

Follow the process of completing the square to solve x^2 - 10x + 8 = 0. What is the value of the constant that will be isolated
My name is Ann [436]
To solve using completing square method we proceed as follows:
x^2-10x+8=0
x^2-10x=-8
but
c=(b/2)^2
c=(10/2)^2=25
thus we can add this in our expression to get
x^2-10x+25=8+25
factorizing the LHS we get:
(x-5)(x-5)=33
(x-5)^2=33
getting the square roots of both sides we have:
x-5=+/-√33
x=5+/-√33

Which of the following is a correct interpretation of the expression -7- (-11)?
Brilliant_brown [7]

Answer:

B. Start at -7 on the number line and move 11 to the right.

Step-by-step explanation:

<u>Given:</u>

  • - 7 - (-11) expression

We can add or remove only positive numbers on the number line to get it  correct, so we need to open the parenthesis. When evaluated we get:

-7- (-11) = - 7 + 11 = 4

<u>Correct interpretation of of this expression is:</u>

  • Start at -7 and add 11, thus move 11 points to the right, to get 4 as final point.

<u>Correct choice is:</u>

  • B. Start at -7 on the number line and move 11 to the right.
