Answer:
the first figure
Step-by-step explanation:
it is closer to 50%
8 tortillas as per the graph
Follow the X line to the right for 4 orders, now go up the Y line to the number of corn tortillas needed indicated by the dot
Here is what to do:
Add like terms. For example, you can add apples to apples, but not apples to oranges. In other words, you can add similar values of x with its others, but not the values of x with regular numbers.
The answer is 3x-3
The range is the resulting y-values we get after substituting all the possible x-values.

Substitute the values of x to the equation of the function:

Note: The equations written in this questions are not appropriately expressed, however, i will work with hypothetical equations that will enable you to solve any problems of this kind.
Answer:
For the system of equations to be unique, s can take all values except 2 and -2
Step-by-step explanation:

![\left[\begin{array}{ccc}2s&4\\2&s\end{array}\right] \left[\begin{array}{ccc}x_{1} \\x_{2} \end{array}\right] = \left[\begin{array}{ccc}-3 \\6 \end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D2s%264%5C%5C2%26s%5Cend%7Barray%7D%5Cright%5D%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7Dx_%7B1%7D%20%5C%5Cx_%7B2%7D%20%5Cend%7Barray%7D%5Cright%5D%20%3D%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D-3%20%5C%5C6%20%5Cend%7Barray%7D%5Cright%5D)
