Answer:
probably 2/4 try it I don't know
Answer:
Ok, this is quite a bit more work than I am used to but I will try!
Step-by-step explanation:
Ok, seeing we have no hidden value for <em>x </em>I presume that we are using it as a coordinate plane listing location. Now that we have that settled, that would mean for the first bit on "A" is y= -4x is starting at x=0 on the number line and we are moving it back 4 spaces. Next bit for "A" is y=2(-x+1) seeing that it is right beside it means it is multiplication and we will be using PEMDAS for this one so we can get the best results. We will start with taking -x which automatically makes it -1x because there is no value infront of it and adding 1 because of +1, you can't have -0 you know! Meaning this value is y=0 because anything times zero is, say it with me! ZEEERROOOO! Now for part B, we moved back to "x" but for both parts... hmm.... well, let's start! -4x=2(-x+1), practically our last question but with multiple "x's". Using same logic, answer is -4x=0, meaning the value of "x" is 0. Turns out last questions "y" variable was an actual variable! Not a piece on the coordinate plane, silly me! Next answer is 0 and after that -4x=2(-x+1) we got the same logic as our last question, almost exact actually! There fore -4x=0! Hope this helped and have a good day! :D
First of all, move all terms to the same side:
You can factor an x, which means that 
is a solution:
This expression is further factorizable if the quadratic equation has any solution. Using the quadratic formula, we can find that they are
So, we have
