What is the inverse function of d(x) = 2x - 4?

Naddik [55]3 years ago

Let d(x) = 2x - 4

Or

y = 2x - 4

We have replace x = y

x = 2y - 4

Now Isolate "y"

x + 4 = 2y

Pass "2" dividing

(x + 4) / 2 = y

y = x/2 + 2

Or

d(x)^-1 = x/2 + 2

What is 2x-y=6 the slope
Flura [38]

First of all, lets get y on its own side of the equation.

-y=-2x+6\\y=2x-6\\

This is slope intercept form, y=mx+b, where m is slope.

we can see that m=2, so the slope is 2 or \frac{2}{1}

Katena32 [7]

Answer:

L = 3√5

Step-by-step explanation:

A square and a rectangle have equal areas.

Area of a square = Area of a rectangle

L² = H * W

If the dimensions of the rectangle are 15 units by 3 units,

L² = 15 * 3

L² = 45

Determine the length of the side of the square.

L = √45

L = 3√5
