Answer:
The Answer is (1,10)
Step-by-step explanation:
First, I saw the operation done on point (5,8), to translate it to point (3,9), then I did this operation again to get the answer.
[The operation I'm talking about is (x-2,y+1)]
So for the two equations: Not sure how hard you want them but....
15+1=16 and 13+ 18=21
For the open equation.
2x + x(5+7)=105
The answer is C. I got it right
Answer: C) Tracy spends $7 every 4 days
Graphing the function as well as x = 4 will show that there is a difference in the y-value of 7 between x=0 and x=4, meaning she spends $7 every 4 days.
8% or 8 cents per dollar.
To find the answer, just divide the extra 32 cents charged by the 4 dollars spent to find the amount per dollar, and you should get 8, or 8% tax.
