Answer:

Step-by-step explanation:
The model shows that there are 40 tiles which were divided into 4 per group. This results into 10 groups. That is:

Therefore, the expression modeled by the arrangement of the tiles is 
I think x = 78
because 21/14 = 1.5
so x = 1.5*52
x = 78
Answer:
Yes its C
Step-by-step explanation:
First off the y intercepts + 3 and the line hits it not -3 so option D is out
Also the slope is negative so Option A and B are out
Answer:
a and c
Step-by-step explanation:
it would be a and c because the first expreesion in the sentace equals 54
<u><em>A and C are the only options that do not equal ( They both equal 24 not 54!) </em></u>

Hello!</h2>
The answer is:
The first option,

<h2>
Why?</h2>
To find the inverse of a function, we need to rewrite the variable "x" with "y" and the variable "y" with "x", and then, isolate "y".
We are given the function:

Write "f(x)" is equal to write "y", so:

Now, finding the inverse, we have:

Hence, we have that the answer is the first option,
