Answer:
$1.25
Step-by-step explanation:
The graph shows that 3 pens cost $3.75 which means each pen costs more than $1 so we know that the greater number will be the numerator in our division equation. Divide 3.75 by 3 to get the unit rate.
3.75/3=1.25
Each pen costs 1.25
You can check your work by plugging it into the other points.
6*1.25=7.5 -So that second point is correct
9*1.25=11.25- The third point is also correct meaning we got the right answer
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!!

If its C I'm sorry That seems correct but I don't know for sure, just my advice!
Answer:
x=9
Step-by-step explanation:
First, distribute the negative sign, changing (2x+9) to -2x-9
next, distribute. 10x+−2x+−9=(−3)(15)+(−3)(−4x)
then, combine like the like terms (10x+−2x)+(−9)=12x−45
then you get 8x+−9=12x−45, and you will subtract 12x from both sides, resulting in −4x−9=−45. To get -4x by itself, add 9 to both sides
lastly, divide both sides by -4
x=9
