In a question, when it states "a number" without giving a real number, that means it's a variable. Variables are normally letters. In the question, it gives you what letter to use, "y". Start the equation.

Current\ Equation: y

The word "decreased" is used when subtracting. In this equation, you are going to be subtracting. Add that to the equation.

Current\ Equation: y-

"Negative" is used for negative numbers. For example, "negative 1" is going to be -1. In the question, it says "negative 7", which is going to be -7. Add that to the equation.

Current\ Equation: y-(-7)

The phrase "Is the same thing as" means equal. Add that to the equation.

Current\ Equation: y-(-7) =

At last, 48. 48 is just 48 as a number. Add that to the equation.

Equation:  y-(-7)=48

Your answer is: y - (-7) = 48

Find the value of two numbers if their sum is 23 and their difference is 5
yKpoI14uk [10]

Let the two numbers be represented by x and y respectively.

Then x + y = 23, and x - y = 5.  

Solve this system of linear equations for x and y.  Start by rearranging them vertically:

x + y = 23

x - y = 5

---------------   Combining the two equations eliminates y:

2x = 28.

Then x = 14.  If x = 14, then 14 + y = 23, and y = 9..

The solution is (14, 9);  that is, x = 14 and y = 9.

Write an equation for the line below. Show work
Gekata [30.6K]

x=3 is your answer. This is because it only crosses the x-axis and this occurs at positive 3. y=3 on the other hand would be a horizontal line that only touches positive 3 on the y-axis.

Consider the equation below (in screenshot)
frozen [14]

The <em>approximate</em> solution of the equation shown in the picture is x ≈ 39 / 8 (Right choice: B).

<h3>How to find an approximate solution of a one-variable equation</h3>

The solution of the equation is between x = 4 and x = 5. Now we begin by evaluating each side of the expression (f(x) = x² - 5 · x + 4, g(x) = 2 / (x - 1)) at the average of x = 4 and x = 5.

x = (4 + 5) / 2

x = 4.5

f(4.5) = 4.5² - 5 · 4.5 + 1

f(4.5) = - 5 / 4

g(4.5) = 2 / (4.5 - 1)

g(4.5) = 4 / 7

The solution of the equation is between x = 4.5 and x = 5, then we evaluate at the average:

x = (4.5 + 5) / 2

x = 4.75

f(4.75) = 4.75² - 5 · 4.75 + 1

f(4.75) = - 3 / 16

g(4.75) = 2 / (4.75 - 1)

g(4.75) = 8 / 15

The solution of the equation is between x = 4.75 and x = 5, then we evaluate at the average:

x = (4.75 + 5) / 2

x = 4.875

f(4.875) = 4.875² - 5 · 4.875 + 1

f(4.875) = 25 / 64

g(4.875) = 2 / (4.875 - 1)

g(4.875) = 16 / 31

The <em>approximate</em> solution of the equation shown in the picture is x ≈ 39 / 8 (Right choice: B).

The sum of two numbers is 8. Is it possible for the difference of the two numbers to also be 8? Why or why not
r-ruslan [8.4K]

Answer: yes

Step-by-step explanation: because you would get the same number cause anything plus or even divided by 0  then 8 each time you try ex: 8 + 0 = 8

8 - 0 = 8
