Answer:
1. k=2
2. b=2f
3. 68
Step-by-step explanation
1. y=kx (replace x&y with 2 values)
12=k(6) (isolate k)
/6 /6
2=k *check with another value to see if k truly is 2
2. since the constant of variation is 2, we can see that 2x the number of flowers make up the birds. so...
b(birds/y-value)=2(constant)f(number of flowers)
b=2f
3. input 34 into f, since there are 34 flowers
b=2*34 (use mental math)
b=68
in other words, there will be 68 birds.
