Which function is the inverse of f(x) = 2x + 3?

lianna [129]

Answer:

y = 1/2x - 3/2

Step-by-step explanation:

The easiest way to find the inverse is to switch x and y and solve for y.

y = 2x + 3

x = 2y + 3 (Switch)

x-3 = 2y (Subtract y from both sides)

x/2 - 3/2 = y (Divide both sides by 2)

Can someone help me with this problem:)

Answer:

Therefore,

93.6 feet tall is the tower from the ground.

Step-by-step explanation:

Given:

x = Opposite side to angle 60

50 ft = Adjacent side to angle 60

7 ft = height of boy

So Height of the tower will be,

$Height\ of\ tower=x+7$

To Find:

Height of the tower = ?

Solution:

In Right Angle Triangle , Tangent Identity we have,

$\tan 60= \dfrac{\textrm{side opposite to angle 60}}{\textrm{side adjacent to angle 60}}$

Substituting the values we get

$1.732= \dfrac{x}{50}\\\\x=86.6\ ft$

Substituting "x" For Height of tower we get

$Height\ of\ tower=86.6+7=93.6\ ft$

Therefore,

93.6 feet tall is the tower from the ground.
