In the expression 4x-5, what is the coefficient?
1 answer:
Answer:
Step-by-step explanation:
<em>⇒A coefficient is an integer that is written along with a variable or it is multiplied by the variable.</em>
<em />
<em>⇒when a term is made up of a constant multiplied by a variable or variables, that constant is called a coefficient. In the term 1x, the coefficient is 1.</em>

Answer:
Because the product is always non-termination,non-repeating decimal.
Step-by-step explanation:
If we have is irrational;
is rational such that
, then
is irrational.
A way to represent this is:
Note that we have a contradiction, because is not a rational number, as I stated in the beginning. Therefore, ab is irrational.
The first step to solving this is to write the number in exponential form

= 
since the bases are the same,, set the exponents equal to one another
-IxI = 7
now change the signs on both sides of the equations
IxI = -7
this equation is false for any value of x because the absolute value function needs to always be positive or 0,, which is not the case for this expression
x ∈ ∅
this means that the answer to your question is x ∈ ∅
let me know if you have any further questions
