What happens to the value of the expression 1+3f1+3f1, plus, 3, f as fff increases? Choose 1 answer: Choose 1 answer: (Choice A)
Leto [7]

Answer:

A. It Increases

Step-by-step explanation:

Given the expression:

1+3f

When f=1, 1+3f=1+3(1)=1+3=4

When f=2, 1+3f=1+3(2)=1+6=7

When f=3, 1+3f=1+3(3)=1+9=10

We can see that the value of the given expression for each successive term increases and in fact form the sequence

4,7,10,...

Therefore, when f increases, 1+3f increases.

What is 20-7n=8(n-2). Please show steps.
ipn [44]

First, you need to distribute the right side of the equation : 8n - 2

Now the equation is : 20 - 7n = 8n - 2

Add 2 to both sides : 22 - 7n = 8n

Add 7n to both sides : 22 = 15n

Divide both sides by 15 : ( I had to round this one) 1.5 = n
