You can pick a question to answer. you don't have to do all of them. plz plz leave a explanation of how you did it. im struggling

You follow the Order of Operations:
P - parenthesis
E - exponents
M - multiplication
D - division
A - addition
S - subtraction

Take #3 for example:

10-18÷3+1

No parenthesis, no exponents, no multiplication, but there's division! -18÷3, which equals -6.
So, now the newly written equation is:
10-6+1
Next, there's addition. -6+1, which equals -5.
Newly written equation:
10-5
Finally, there's subtraction.
10-5=5
So, the answer is 5.

All except for b, because polynomial functions can be quadratic, cubic, witticisms and etc only non negative exponents of negative it is not a polynomial function

You would need a laid out graph for this but could you provide a picture of just a graph? i can give stepssolve for y.subtract 4xdivide by -1 (opposites)graph slope intercept formcheck each point to see if it’s on the graph
