What is Subtraction?Subtraction can be done for any numbers or algebraic expressions. It is the process of taking out certain value from a given amount of number.
The process of subtraction can also be termed as finding difference.
Given is an expression 10x - 2x.
We have to find the difference of these two expressions.
We can add or subtract only the like terms.
Like terms are terms which consist of same kind of variables.
Here 10x and 2x have same variable x.
So they can be subtracted.
10x - 2x = x(10 - 2) = 8x
Hence the difference of 10x and 2x is 8x.

Evaluate the equation for the indicated value, f(n)=5n+8 for f(4),
The value of the function f(n)=5n+8 for f(4) will be 28.
What is a function?A function is defined as the expression that set up the relationship between the dependent variable and independent variable.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given function is f(n)=5n+8. The value of the function at equal to 4 will be calculated as below:-
f(n)=5n+8
f(4) = ( 5 x 4 + 8 )
f(4) = 20 + 8
f(4) = 28
Therefore, the value of the function f(n)=5n+8 for f(4) will be 28.

i believe it's A. f(x) slope is greater than g(x) slope
Step-by-step explanation:
the slope of f(x) is -2, while g(x) is -6. you may think "why isn't -6? 6 is bigger, isn't it?" In this case, they're both negative so the number closer to zero is the greater one

Step-by-step explanation:
What percent of $18 is $6?
33.333% (with the 3 repeating)
1/3 of 18 is 6, so 33.333% (with the 3 repeating) of 18 would be 6.
Answer:
33.333% (its a repeating 3)
Step-by-step explanation:
$6 is 33.33% of 18.
I got this number by dividing 6 by 18, which gave me 0.33333333333.
I then converted 0.33333333333 to a percentage, rounded, and got 33.33%.
Please answer. Which is the graph of the solutions.
Answer:
x < -8, third from top option in the picture.
Step-by-step explanation:
5(2x - 4) < -100
10x - 20 < -100
10x < -80
x < -8
Answer:
3rd option from the top (open circle arrow going left)
Step-by-step explanation:
5(2x-4) is less than - 100
5 times 2x is 10x and 5 times - 4 is - 20 so,
10x - 20 is less than - 100
now do inverse operations to isolate x, add 20
- 20 plus 20 is 0 and -100 plus 20 is - 80
10x is less than -80
divide both sides by 10 and you get,
x is less than - 8
