Two lines, E and F, are represented by the equations given below.
shusha [124]
Although you have not included the statements about the solution to the set of the given equations, I can explain you what happen with that system.

You can arrive to the same conclusion by any method of solution of systems that you like.

The quickest in this case, is to multiply the equation of the lIne F by 5.

That leads to: 5 (x + y) = 5(8)

⇒ 5x + 5y = 40.

Now you can realize that the two representations (equations) correspond to the same line.

That means that there are infinite solutions, this is infinity values of x and y meet both equations.

If you graph line E and line F they overlap in the entire domain, so the graphing method also tells you that you cannot find one solution but infinite soluttions.

Letter grades earned by a particular student in history class.

Consider a population whose growth over a given time period can be described by the exponential model: dN/dt = rN. Select the co
pantera1 [17]

Answer:

b and c

Step-by-step explanation:

We are given that a population whose growth over a given time period can be described by the exponential model

\frac{dN}{dt}=r N

Let initial population =N_0 when time t=0

\int\frac{dN}{N}=r\int_0^tdt

After integrating

We get ln N=rt +C

Where C is integration constant

When t=0 then N=N_0

ln N_0=C

Substitute the value of C then we get

ln N=rt +ln N_0

ln N-ln N_0=rt

ln\frac{N}{N_0}=rt

\frac{N}{N_0}=e^{rt}

N=N_0e^{rt}

When r=0.1 then we get

N=N_0e^{0.1t}

Hence, the population increase not decrease.

When r= 0

Then we get

N=N_0e^{0}

N=N_0

Hence, the population do not increase or decrease.

So, a population with r of 0 will have no births or deaths during the time period under consideration.

If we take a positive value of r then the population will increase exponentially .

Hence, option b and c are both correct.
