Answer:Because its -2x exponent of 2 so you cant do anything to that but you can touch the 2x it doesn't have a exponent so that's why but now since you did something to 2x you have to change 2x exponent of 2 into negative

Step-by-step explanation:

2x² + 2x + ? = x

⇒ ? = x - 2x² - 2x

⇒ ? = -2x² - x

Your answer is incorrect because 2x² - x² would mean x² is part of the answer, which is clearly incorrect.

This question is pretty confusing in the way that i'm not entirely sure what it wants the answer to be, but i'll do my best.

i used the simple interest formula to come up with the equations, and the formula is I = PRT, (I) being interest, (P) being the amount, (R) being the rate of interest, (T) being the time, in months

b = the balance on the customer's account
c = service charge
t = number of months

if b > 1000, then c = b*.008t
if b </= to 1000, then c = b*.012t
if b < 50, then c = t
if b = 0, then c = 0

it looks really confusing but i'm hoping it's lining up with what you're learning and not completely ?????

i created the restrictions with the inequalities based on the given information of what happens when a balance exceeds 1000, is less than 1000, is less than 50, and is 0.

i used the remainder of the given information in the problem to get the equations -- the interest rate for b > 1000 is 0.8%, which is .008, b </= 1000 is .012, and so on. i hope this wasn't too terribly confusing, and let me know if you have any questions about how i came up with the equations!!

Will give Brainliest!!!<br> What is the y=mx+b for the equation x−y=−8?
mafiozo [28]
First add y on both sides to get x = y-8, then add 8 on both sides to get x + 8 = y. thats really all you can do because you don't have the slope, so it ends up being y = mx+8
