Answer:
The expression for two times the difference of 4 and a number is

Step-by-step explanation:
To Find:
Write an expression for Eight times the difference of 4 and a number.
Solution:
Let the Unknown number be 'd'
Difference of 4 and d = ( 4 - d )
So One Time Difference of 4 and d = 1× ( 4 - d )
∴ Two Times Difference of 4 and d = 2× ( 4 - d )
∴ Eight Times Difference of 4 and d = 8× ( 4 - d )
The expression for Eight times the difference of 4 and d. will be

The expression for Eight times the difference of 4 and a number is

5 hundreds is 500. So 500x10= 5000.
Answer:5000
The solution of a linear inequality is the ordered pair that is a solution to all inequalities in the system and the graph of the linear inequality is the graph of all solutions of the system. Graph one line at the time in the same coordinate plane and shade the half-plane that satisfies the inequality.
Answer:


Step-by-step explanation:
<u>Composite Function</u>
Suppose f(x) and g(x) are real functions, the composite function named
is defined as:

The composite function can be found by substituting g into f.
We are given these functions:



Find:
a) h(g(x))
Substituting g into h:

b) h(g(f(x))
First we find g(f(x)):

Operating:

Simplifying:

Now find h(g(f(x)) replacing the above equation into h:

Simplifying and rearranging:
