Which equation can pair with x-y=-2 to create a consistent and dependent system?

Mathematics

MrRissso [65]3 years ago

See the explanation

<h2>Explanation:</h2>

A system that has one or infinitely many solutions is called <em>consistent. </em>If an equation in a system tells us no new information then the equations of the system are <em>dependent. </em>In other words, to find an equation that creates a consistent and dependent system with the given equation we have to get the same line:

The given line is:

x-y=-2

If we multiply both sides of the equation by a constant we will have the same line when plotting, therefore let's multiply by 3:

3(x-y)=3(-2) \\ \\ 3x-3y=-6

So a system of two linear equation that is consistent and dependent is:

\left \{ {{x-y=-2} \atop {3x-3y=-6}} \right.

The function that represents bruce’s elevation in feet over time in hours is an exponential function that starts at 1,505 feet.
Strike441 [17]

Answer:

<h3>The function for Bruce’s elevation is f(x)=1505(6)^x and because b=6 that is greater than 0, it is an exponential growth function.</h3>

Step-by-step explanation:

We are given initial Bruce’s elevation = 1,505 feet.

Each successive hour, his average elevation change for the hike becomes 6 times the previous hourly elevation change.

We know, the exponential function f(x)=a(b)^x, where a is the initial value, b is the growth factor and x is the exponent represents time in hours.

Therefore, initial value a=1505, growth factor b for exponential function f(x)=a(b)^x is 6.

Plugging a=1505 and b=6 in f(x)=a(b)^x , we get

f(x)=1505(6)^x

Also note, if b>0, it would be an exponential growth function.

<h3>Therefore, the function for Bruce’s elevation is f(x)=1505(6)^x and because b=6 that is greater than 0, it is an exponential growth function.</h3>

The lifetime of a machine part has a continuous distribution on the interval​ (0, 50​) with probability density function​ f, whe
Strike441 [17]

Answer:

Probability that the lifetime of the machine part is less than 13 = 0.6782

Step-by-step explanation:

given that f(x)=(10+x)^{-2}

Normalizing the function we get

\int_{0 }^{50}cf(x)dx=1

\int_{0 }^{50}c(10+x)^{-2}dx=1

\therefore a=\frac{1}{\int_{0 }^{50}(10+x)^{-2}dx}

\therefore a=12

P(x< 13)=\int_{0}^{13}12(10+x)^{-2}dx\\\\P(X< 13)=0.6782
