Answer:
x= 10 and y= -1
Step-by-step explanation:
Rewrite your second equation Y= -2x+ 19 then plug it into the first equation.
x- (-2x + 19) = 11
x + 2x - 19 =11
3x - 19 = 11
3x = 30
x = 10
The plug that answer into the first equation and solve.
10 - y = 11
-y = 1
y = -1
Given:
The function f(x) describes the amount of money, in dollars, the club will earn for wrapping x presents.

To find:
The f(658).

Therefore,
.
