Answer:
2.4x-4.4
Step-by-step explanation:
The first step to simplify this expression is to expand the terms in parenthesis
Hey I have posted a picture the method I use to solve simultaneous equations is change the sign and follow the new sign.
This involves changing the sign for the second equation and solving it
So basically you are going to line up your equations (already done). Next, you will just add each term. So x + 3x = 4x, then 2y - 2y = 0 (we wouldn't put anything) then 7 - 3 = 4
So then we have all of our terms figured out and will have 4x = 4 then divide 4x by 4 to get x alone and then you will also divide the four that is by itself by four to equal one. So, your answer is x = 1. I hope that helps!
Answer: I believe it is D
Why: Domain=x which gets rid of A, and C and because you cannot really now how many tickets you will sale (like B states certain numbers not the range of possibility) I think it’s D
