|x - 2| + 3 = 10
Solve x-2 + 3 = 10, which gives you x=9
Then solve -(x-2)+3 = 10, which gives you x=-5
f(x)= 2x + 1
Use the function shown above to find the value of f(-2).__________
Substitute x=-2 and get f(-2) = 2(-2)+1 = -3
g(x) = 4x - 5
Use the function shown above to find the value of g(0).__________
Substitute x=0 and get g(0) = 4(0)-5 = -5
Find the solution to the equation.
3x - 2 = 9: 3x = 11 => x=11/3

$280 / 3 hours = $ x / 16 hours
x = 280*16/3 = $1493.33

|x-2| + 3 = 10
|x-2| = 7
-x+2 = 7 or x - 2 = 7
-x = 5 or x = 9
answer x = -5 or x = 9
f(-2) = 2*-2 + 1 = -3
g(0) = 4*0 - 5 = -5
3x - 2 = 9
3x = 11
x = 11/3
Proportion:
x/9 = 1/5
x = 9/5
$280 / 3 = x / 16
3x = 4480
x = 1493.33
rounded: 1493.

You "swear" huh? Sounds like you're defending yourself. Must have a guilty conscience.
Letting someone else do your work gets you -nowhere!
