Answer:
20.922
Step-by-step explanation:
Evaluate ln 7.2 on a calculator; the correct result is 1.974.
Multiply that by 3, obtaining 5.922.
Finally, add 15 to that result: y = 15 + 3 In 7.2 = 20.922
2/3
Divide the numerator and denominator by their gcd which is 5
As we have to solve for b, it means we have to isolate b
So first of all subtract 
from both sides
So we get
Now we need b , but its b^2 , so we can take square root on both sides.
taking square roots on both sides
Hence option B is correct
Answer:
b. {(-1.5, 9.5), (1,7)}
