-4
Answer:
a) (-2,-2)
b) (0,1)
Step-by-step explanation:
(0,-5) is the vertex of the initial function.
(0-2,-5+3)
(-2,-2)
(0,-5)
Reflected in the x-axis : (0,5)
4 units down: (0,1)
Given that:
The function to represent the growth of Neveah hair is
where, x represents the number of months since her last hair cut.
To find:
The inverse of function and time when her hair will have grown 6 inches.
Solution:
We have,
Put f(x)=y.
Interchange x and y.
Isolate y.
Put .
So, the required inverse function is . It represents the number of months to grow her hair x inches.
She can predict when her hair will have grown 6 inches by putting x=6 in the inverse function.
Put x=6 in the inverse function.
Therefore, growth of her hair is 6 inches in 7 months.
The answer if D
100 divided by 30 times 18 equals 60
Answer:
Step-by-step explanation:
6(6x+6)-5 = 1+6x
36x+36-5 =1+6x
36x+31 = 1+6x
-6x -6x
30x+31 = 1
-31 -31
30x = -30
________ (divide)
30
x=-1
