Answer:
Step-by-step explanation:
Given function.
To find the inverse function
Step 1:
Replace with in the function.
Step 2:
Interchange with in the equation.
Step 3:
Solve for .
We have
Adding 4 to both sides,
Dividing each term by 6 to isolate
Simplifying fractions by dividing the numerator and denominator by their GCF.
Thus the equation of is:
Step 4:
Replace with
(Answer)
Thus, we have the inverse function
Answer:
The best thing to do here is to put each of these into fractions, with the total (31) as the denominator.
14/31= silver
6/31= black
8/31= copper
3/31= various colours.
As you're looking for the keys that are silver or copper, you've got to add the two denominators together, which gives you 14+8= 22.
This cannot be simplified further, therefore, the probability of choosing either a silver or copper key is 22/31.
Hope this answer helps you :)

Answer:
1/3
Step-by-step explanation:
DB=6
AB=AD+DB=12+6=18
DB/AB=6/18=6/(6*3)=1/3
DB/AB=1/3
Start at (0,-3) then go up 4 and to the right by 1. Plant a dot there and then draw a line from that point through (0,-3)
