Kristy asks Lonnie to think of a number , Add 3 to it, multiply the sum by 2, and then subtract 6. Let n stand for lonnie's star
Zanzabum

Answer:

2(n+3) - 6 = 2n

Step-by-step explanation:

Let n stand for lonnie's starting number.

Kristy asks to add 3 to the number. It will become (n+3)

Now he ask to multiply the sum by 2. It will become 2(n+3).

Finally, he ask to subtract 6. It will become 2(n+3) - 6

The expression is : 2(n+3) - 6.

We can simplify it as follows :

= 2n+6-6

= 2n

Hence, the required expression is 2n.

Function F(x)=x+1 and g(x)=5x+1 find the f(4)=g(x+1)
Lapatulllka [165]

The function of f(4) = g(x+1) gives the value of x that is -1/5.

<h3>What is the function addition?</h3>

It is the addition of two functions similar to the addition of any two polynomial functions.

Given;

F(x)=x+1

g(x)=5x+1

We need to find f(4)=g(x+1)

First substitute x = 4 in f(x)

F(x)=x+1

F(4) = 4 + 1

F(4) =  5

Now substitute x = x + 1 in g(x)

g(x)=5x+1

g(x + 1) = 5(x + 1) + 1

g(x + 1) = 5(x + 1) + 1

g(x + 1) = 5x + 5 + 1

g(x + 1) = 5x + 6

Then ,

F(4) = g(x + 1)

5 = 5x + 6

5x = 5 - 6

5x = -1

x = -1/5.

The function of f(4) = g(x+1) gives the value of x that is -1/5.

What is the relationship between partitions and number series
vovangra [49]
A sum of positive natural numbers adding up to n is called a partition of n. For instance, 1+2+4 is a partition of 7. As none of the summands 1, 2, 4 are equal, this is called a partition into unequal parts. Does this help? Because this is all I know :(
