we are given

$2x+6=6x-2$

we will isolate x

so, firstly we will move all x terms on any one side

We will add both sides 2

$2x+6+2=6x-2+2$

$2x+8=6x$

now, we can subtract both sides 2x

$2x+8-2x=6x-2x$

$8=4x$

$4x=8$

now, we can divide both sides by 4

and we get

$x=2$ ......Answer

Answer:

$P(x) = 16x - 100 - 0.1x^2$

Step-by-step explanation:

Given

$R(x) = 46x$

$C(x) = 100 +30x +0.1x^2$

Required

Determine the profit function

This is calculated as follows:

$P(x) = R(x)- C(x)$

Substitute values for R(x) and C(x)

$P(x) = 46x - (100 + 30x + 0.1x^2)$

Open bracket

$P(x) = 46x - 100 - 30x - 0.1x^2$

Collect like terms

$P(x) = 46x - 30x - 100 - 0.1x^2$

$P(x) = 16x - 100 - 0.1x^2$

The locations in a city are mapped out on a grid, where the origin represents the city center. A traffic helicopter travels due

Elenna [48]

Answer:

Helicopter have traveled 5.55 units of distance approximately if it went directly from one location to the other.

Step-by-step explanation:

We are given the following in the question:

A traffic helicopter travels due north and then due east to get to the location at (-3,4) to the location at (7,13).

The attached image shows the path of helicopter.

Distance Formula:

$(x_1,y_1), (x_2,y_2)\\\\d = \sqrt{(x_2-x_1)^2 + (y_2-y_1)^2}$

Distance traveled by helicopter =

$d((-3,4),(-3,13)) + d((-3,13),(7,13))\\\\=\sqrt{(-3+3)^2 + (13-4)^2} + \sqrt{(7+3)^2 + (13-13)^2}\\= 9+10\\= 19 \text{ units}$

If the helicopter goes directly:

$d((-3,4),(7,13))\\\\=\sqrt{(7+3)^2+(13-4)^2}\\\approx 13.45 \text{ units}$

Difference in distances =

$19 - 13.45 = 5.55\text{ units}$

Thus, helicopter have traveled 5.55 units of distance approximately if it went directly from one location to the other.
