Answer:
d. 14 -3x
Step-by-step explanation:
If you want to substitute for y in the second equation, you must use the first equation to find an expression for y.
3x +y = 14 . . . . . . first equation
y = 14 -3x . . . . . . subtract 3x from both sides
This gives you the expression for y that you want to use for substitution. It matches the expression of choice D.
y = 14 -3x . . . . matches D
To convert this equation into slope intercept form simply distribute the number of -2 and put it in
Y = mx + b form
Y + 4 = -2(X-1)
Y + 4 = -2x + 2
Y = -2X + 2 - 4
Y = -2X - 2
I believe this is the solution in slope intercept form.

Answer:
$4.25
Step-by-step explanation:
According to the question,she paid $0.25 for one day overdue,
So she kept the book for 17 days so we are to determine the amount he paid for the overdue
1 day=$0.25
17 days=x
Cross multiply
x=17×0.25
x=4.25
So she will have to pay $4.25 for 17 days overdue
