When your doing tax the tax is 9.25 you divide that by 100
the add that to your price then 12.5 divided by 100 and subtract that from what you ended up with so you should come out with a total of 4.22
if you were to use the first ordered pair, your answer would be y - 2 = 11/3(x-7) and with the second ordered pair : y + 9 = 11/3(x-4
FG : (3,7)(-4,-5)
slope = (-5 - 7) / (-4-3) = -12/-7 = 12/7
y = mx + b
slope(m) = 12/7
(3,7)...x = 3 and y = 7
now we sub, we r looking for b, the y int
7 = 12/7(3) + b
7 = 36/7 + b
7- 36/7 = b
49/7 - 36/7 = b
13/7 = b
so ur equation is : y = 12/7 + 13/7.....slope = 12/7, y int = 13/7
HI : (-1,0)(4,6)
slope = (6 - 0) / (4 - (-1) = 6/5
no need to go any farther.....these lines have different slopes...and their not negative reciprocals....so there will be one solution. Answer is : neither.
0.9801. The "9801" is repeatin so just draw the repeating bar above those numbers.

- The first page can be represented by 2n
(Note : We know for certain it is an even number as anything multiplied by 2 is even)
The second page can be represented by 2n + 2
Let's form an equation:
2n + 2n + 2 = 410
Simplify by collecting like terms :
4n + 2 = 410
Subtract 2 from both sides :
4n = 408
Divide both sides by 4:
n = 102
Substitute this value into our earlier expressions
2(102) = 204
2(102) + 2 = 206
The page numbers are 204 and 206
Have A Nice Day ❤
