Answer:
0 < x < 6
Step-by-step explanation:
<u>triangle sides:</u>
other sides subtracted < third side < other sides added
4-3 < x+1 < 4+3
1 < x+1 < 7
1-1 < x+1-1 < 7-1
0 < x < 6
Hope this helps :)

Since one page cost $1.25 to print take the cost of per page $1.25 times the number of pages to be printed, in this case eight. $1.25 x 8 = $10.00
Remember there is still a $3.50 added to the cost of the pages printed; thus you have $10.00 + $3.50 = $13.50 which is the total charge.
Subtract b from each side to get
y
−
b
=
m
x
. Next, divide each side by
x
to get
y
−
b
x
=
m
.
4x - 7y = 1
if y = 5
4x - (7*5) = 1
4x - 35 = 1
4x = 36
x = 9
other coordinate is 9
