Answer:
x = 1.6
Step-by-step explanation:
0.6x + 1.3x = 3.04
1.9x = 3.04
x = 3.04/1.9
x = 1.6
Answer:
g(-1) = 3, g(2) = 6, g(5) = 4
Step-by-step explanation:
Please refer to attached photo. (Apologies for the terrible handwriting.)
From here we can see,
g(x) = x + 4 applies for values x less than or equal to 2.
g(x) = 9 - x applies for values x more than 2 (which does not include 2.)
g(-1):
Since -1 < 2,
g(-1) = -1 + 4 = 3
g(2) = 2 + 4 = 6
g(5):
Since 5 > 2,
g(5) = 9 - 5 = 4
Answer: f^ -1 = x-9/2
Explanation & Steps:
1) Change f(x) to y
2) Switch y and x -> you will get x= y + 9/2
3) subtract 9/2 on both sides -> you will get x-9/2= y
Result- y = x-9/2
(Switch y to f^-1)
Hope this helps :)
To get 1/10 -> 1000/10 =100
and 1% of 100 -> 100/100 = 1 or 1%
100 for question 1
1 for q2
