Answer:
Step-by-step explanation:
The graph of the absolute value function looks like a V that opens UP and has its vertex at the origin, (0, 0). There are no restrictions on the input, x, so the domain is (-infinity, infinity).
On the other hand, this function has no values less than zero. Its range is
[0, infinity).

Answer:
- $400 at 2%
- $900 at 3%
- $3600 at 4%
Step-by-step explanation:
Let x represent the amount invested at 3%. Then (x -500) is the amount invested at 2%, and 4x is the amount invested at 4%. The total interest income is ...
0.02(x -500) + 0.03x + 0.04(4x) = 179
0.21x -10 = 179 . . . . . simplify
0.21x = 189 . . . . . . . . add 10
x = 900 . . . . . . . . . . . divide by 0.21
x -500 = 400
4x = 3600
$400 is invested at 2%; $900 is invested at 3%, $3600 is invested at 4%.
Six two point shots is 12 points.
of the 21 scored, that leaves nine points, or three 3-point shots. (If my math is right)
