Answer:
Option 3.
Step-by-step explanation:
The given function is

where, x is number of coupon books.
We have to find the practical domain for the given function.
Domain : The set of input values is called domain.
It is given that Raul is selling coupon books. He started with 50 coupon books and has already won a prize for selling at least 10 coupon books.
The number of coupon books can not be a decimal or fraction value. It means the values of x are integers.
The value x is all integers from 10 to 50.
Hence, the correct option is 3.
Given: f(x)=(2x-2)/4
find f^-1(3)?
we need to find the inverse of f(x), so
x=(2y-2)/4
2y-2=4x
y-1=2x
y=2x+1
so, then f^-1(x)=2x+1
f^-1(3)=2(3)+1
=6+1
=7
so, the answer is 7
Answer:
m∠ABC = 130°
Step-by-step explanation:
BD is the angle bisector of angle ABC .
Therefore, ∠ABD ≅ ∠DBC
Measure of angle DBC = 65°
Therefore, m∠ABD = m∠DBC = 65°
m∠ABC = m∠ABD + m∠DBC
= 65° + 65°
= 130°
