All you have to do is the amount she bought divided by 0.05 and then add the answer you get to the amount she bought each time
Answer:
F^-1 (x) = 3x/2+5/4
Step-by-step explanation:
First, replace f(x) with y
Replace every x with a y and replace every y with an x .
Solve the equation from Step 2 for y
Replace y with f−1(x) f − 1 ( x )
Verify your work by checking that (f∘f−1)(x)=x ( f ∘ f − 1 ) ( x ) = x and (f−1∘f)(x)=x ( f − 1 ∘ f ) ( x ) = x are both true.
Hope this helps! Stay Safe!
Factor it out first so:
y=(x+13)(x-2)
Then you know that x= -13 and 2 to make the equation 0
Hope this helps!
Answer:
Step-by-step explanation:
Let the number of blue marbles be x
The number of green marbles = 3x - 2
Total marbles= 18
x + 3x -2 = 18
4x - 2 = 18
4x = 18+2
4x = 20
x =20/4
x =5
The number of blue marbles = 5
The number of green marbles = 3*5 - 2 = 15 -2 = 13
