Answer:

No Solution

Step-by-step explanation:

x+2=x+4

So first substract x by both sides.

x-x+2=x-x+4

2=4

There is no way that 2 is equal to 4 so therefore, the equation has no solutions.

Is the following a fixed or a variable expense?

nekit [7.7K]

Answer:

Fixed Expense (A)

Step-by-step explanation:

Typically fixed expenses incorporate car payments, lease or rent payments, insurance premiums, and real estate taxes. Typically, these expenses can't be simply changed. On the positive side, they're simple to budget for because they regularly stay the same and are paid on a daily basis.

A particle is moving along the curve y= 4sqrt(5x+11) . As the particle passes through the point (5,24) , its -coordinate increas

kupik [55]

The rate of change of the distance from the particle to the origin at this instant is 3 units per second.

<h3>What is the rate of change?</h3>

The instantaneous rate of change is the rate of change at a particular instant.

A particle is moving along the curve

$y= 4\sqrt{5x+11} .$

The rate of change of y is given as:

dy / dx = 2

by differentiating both sides,

$\dfrac{dy}{dx} = 4\dfrac{1}{2\sqrt{5x+11} } 5\dfrac{dx}{dt} \\\\\dfrac{dy}{dx} = \dfrac{10}{\sqrt{5x+11} }\dfrac{dx}{dt}\\\\$

From the question, we have:

(x, y) = (5,24)

Substitute 5 for x and dy / dx = 2

$\dfrac{dy}{dx} = \dfrac{10}{\sqrt{5x+11} }\dfrac{dx}{dt}\\\\\\5= \dfrac{10}{\sqrt{5(5)+11} }\dfrac{dx}{dt}\\\\\\\sqrt{5(5)+11} = 2\dfrac{dx}{dt}\\\\\\\dfrac{dx}{dt} = 6/ 2 = 3$
