Answer:
The answer is: always
Step-by-step explanation:
All numbers even irrational numbers are real numbers.
Hope it helps!
Given:
In a number, adding 
, then multiplying the result by 
we get 8.
To find:
The unknown number.
Solution:
Let the unknown number be x.
According to the question,
Multiply both sides by 
.
Subtract 
from both sides.
Therefore, the required number is 
.
Answer: y = f(m)
Justification:
By definition, the graph of a function in the cartesian coordinate plane is the plot of the curve that join all the points that satisfy the equation of the function.
In the cartesian coordinate plane, each point is represented by a pair of coordinates (y, x). y is the value of the function f(x), and x is any input value of the function.
In this case, the function is given as f(m), which means that the input value is represented by m.
Hence, the graph is the plot of y = f(m).
The choice of the letter used for the variable is completely arbitrary and does not change either the math or the graph. It could have been said that the function is f(x) in which case the graph would be y = f(x). Nothing changes but the name that you use.
Answer:
Correct choice is C). mn=ac
Step-by-step explanation:
Given statement is that the first step in factoring a trinomial of the form is to find two numbers, m and n, such that m + n = b and _____.
We know that when we factor polynomial of type 
,product of both numbers m and n must be same as product of a and c.
Hence correct choice is C). mn=ac
