<span>f(x)=3[x-2]
So, f(5.9) = ?
f(5.9) = 3(5.9 - 2)
=3(3.9)
=11.7 = 12
Thus, the answer is 12.

Answer: 12
Step-by-step explanation:
We know that , the ceiling function y = [x] is also known as the least integer function that gives the smallest integer greater than or equal to x.
For example : For x= 1.5
y = [1.5] =2
For x= 3.64
y = ⌊3.64⌋=4
The given function : ![f(x)=3[x-2]](https://tex.z-dn.net/?f=f%28x%29%3D3%5Bx-2%5D)
Then, for x= 5.9 , we have
![f(5.9)=3[5.9-2]\\\\ f(5.9)=3[3.9]\\\\ f(5.9)=3(4)=12](https://tex.z-dn.net/?f=f%285.9%29%3D3%5B5.9-2%5D%5C%5C%5C%5C%20f%285.9%29%3D3%5B3.9%5D%5C%5C%5C%5C%20f%285.9%29%3D3%284%29%3D12)
[since [3.9]=4 (least integer function)]
Therefore, the value of f(5.9) is 12

Step-by-step explanation:
Answer:
m=17
Step-by-step explanation:
$15 minus $0.14(# minutes) = $12.62
15 - .14m = 12.62
.14m = 15 - 12.62
.14m = 2.38
m = 2.38/.14
m = 17 minutes
Brung like terms together:-
1/4 y - 1 3/4 y + 11/2 + 2 - 12
= - 1 1/2 y + 11/2 - 10
= - 1 1/2y - 9/2
The inverse operation is subtraction
