Answer:

Step-by-step explanation:

Ok, so i cant really awnser all the questions on that page but a very important thing to know is that it is proportinal if the layout is y=mx. the m is usually replaced with something else though. So for that first question, its proportianal. Try your best to turn those story problems into equations and then see if it matches the y = mx equation if not, its not

The number of comic books is an illustration of a linear function

The complete equations are: $\mathbf{8b + 17 =65}$ and $\mathbf{b =6}$
The value of b has increased by 4

She had 17 comic books already.

So, we have:

$\mathbf{Base\ Amount = 17}$

Her order of 65 books contains 8 comic books per collection.

So, we have:

$\mathbf{Rate = 8}$

$\mathbf{Total = 65}$

This is represented as:

$\mathbf{Rate \times b + Base\ Amount =Total}$

So, we have:

$\mathbf{8\times b + 17 =65}$

Rewrite as:

$\mathbf{8b + 17 =65}$

Subtract 17 from both sides

$\mathbf{8b =48}$

Divide both sides by 8

$\mathbf{b =6}$

Assume she has 97 books in her collection, then the equation would be represented as:

$\mathbf{8b + 17 = 97}$

Subtract 17 from both sides

$\mathbf{8b = 80}$

Divide both sides by 8

$\mathbf{b = 10}$

The values of b are 6 and 10.

The difference between 6 and 10 is 4

Hence, the value of b has increased by 4

A sofa is on sale for $703 which is 24% less than the regular price what is the regular price

Firdavs [7]

Hello!

We could write this as an equation below.

0.76x=703

We divide both sides by 0.76.

x=925

Therefore, the regular price is $925.

I hope this helps!
