Which represents the inverse of the function f(x) = 4x?

Dmitry_Shevchenko [17]

F (x) = 4x ⇒ y = 4x
↓
x = 4y Divide by 4 on both sides
↓
x / 4 = y ⇒ Inverse function = x / 4

Answer:

R2 = 6.44

T2 = 8.82

Whole = 30.42

Step-by-step explanation:

R1 = 2.8 X 3.1

T1 = (1/2) X (2.4) X (5.4)

R2 = (5.4-3.1) X (2.8) = 6.44

T2 = (1/2) X (11.7-5.4) X (2.8) = 8.82

Whole = (1/2) X (11.7) X (2.4+2.8) = 30.42

What is the distance between the point (−10, −2)(−10, −2) and the point (−4, −2)(−4, −2) ?

Gnoma [55]

In this case: x 1 = - 10, y 1 = - 2;
x 2 = - 4 , y 2 = - 2
The distance between the points :
$d = \sqrt{(x 2 - x 1 ) ^{2} + ( y 2 - y 1 ) ^{2} } = \\ =\sqrt{(-4+10) ^{2} +(-2+2) ^{2} } = \\ = \sqrt{6 ^{2}+0 ^{2} } = \sqrt{36}= 6$
Answer: d = 6
