It will take 7 weeks and both will have $610
30x7=210+400=610
55x7=385+225=610
4(c+2)<4c+10
4c+8<4c+10
-4c -4c
--------------------
8<10
Which gives you No Solution.
Answer:
domain of f(x) is x ≤ 0; domain of f^-1(x) is x ≥ 4
Step-by-step explanation:
The square root function will always give a positive value, so the opposite of the square root function will give non-≤positive values. That means ...
- the domain of f(x) is restricted to non-positive values
- the domain of the inverse function is restricted to values of x that make the root be of a non-negative number: x ≥ 4
The domain of f(x) is x ≤ 0; the domain of f^-1(x) is x ≥ 4.
The distance around the bulletin board would be 20 feet, because you multiply 6ft 2x and 4ft 2x.
