Answer:
The answer to your question is f⁻¹(x) =
Step-by-step explanation:
Function
f(x) = 2x + 3
Process
1.- Instead of f(x) write y
y = 2x + 3
2.- Interchange the variables
x = 2y + 3
3.- Solve for y
- Subtract 3 in both sides
x - 3 = 2y + 3 - 3
x - 3 = 2y
- Divide by 2
4.- Write f⁻¹(x) instead of y
f⁻¹(x) =
Answer:
The absolute decrease was of 33 million.
The relative decrease was of 22.45%.
Step-by-step explanation:
Absolute change
The absolute change is the number of CD's sold is the number of CD's sold in 2010 subtracted by the numbers of CD's sold in 2009.
The number is negative, which means that there was a decrease.
114 million - 147 million = -33 million
The absolute decrease was of 33 million.
Relative change
The relative change is the absolute change divided by the initial value.
So -33/147 = -0.2245
Which means that the relative decrease was of 22.45%.
4) because 10 x 10 is 100
Let’s say that the alleles are B’s. The alleles are different, so it would be Bb. Cross two of them to get BB, Bb, Bb, and bb. Blue eyes are homozygous recessive, or bb. There is a 1 in 4 chance of having a blue eyed child, or 25%.
