7 shirts
Step-by-step explanation:
First, you’d do 10$ spent on lunch and the 35$ spent on the jeans or pants. You add those together to get 45$. You then subtract that from $134.25. Your answer should be $89.25. Now, divide 89.25 by 12.75 to get 7. 7 shirts!
The number opposite of 0 is -0
You can put the 2points into a graph in your calculator and do the slope y1~mx1+b it will give you your equation which is y= 2x - 2
The general formula for exponential growth and decays is:

if k>0 then then it is an exponential growth function. If k<0 then the function represents an exponential decay.
Now we need to classify each of the functions:
1.
The function

can be wrtten as:

comparing with the general formula we notice that k=2, therefore this is an exponential growth.
2.
The function

can be written as:

comparing with the general formula we notice that k=-4, therefore this is an exponential decay.
3.
The function

comparing with the general formula we notice that k=-1, therefore this is an exponential decay.
