Which represents the inverse of the function f(x)=2x+1

The inverse of the equation is f(x) = (x - 1)/2

In order to find the inverse of any function you need to first switch the x and f(x). Then you solve for the new f(x) and that's your inverse.

f(x) = 2x + 1 > Switch the f(x) and x

x = 2f(x) + 1 > Subtract the 1

x - 1 = 2f(x) > Divide by 2

(x - 1)/2 = f(x)

hope this !

step-by-step explanation:

d = distance between moon and sun, which in this problem is the hypotenuse of a right triangle.  

the distance y is the side opposite to angle x in the right triangle.   use the definition of the sine function from basic trigonometry.

sin(x) = y/d ⇒

d = y/sin(x)

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
