Y=4x and 3x+y=-21. Substitute

gizmo_the_mogwai [7]

value of x= -3 and value of y = -12

Solution set is (-3,-12)

Step-by-step explanation:

We need to solve the system of equations using substitution

The system of equations are:

$y=4x\\3x+y=-21$

Solving:

Let

$y=4x\,\,eq(1)\\3x+y=-21\,\,eq(2)$

Solving:

Putting value of y from equation 1 into equation 2

$3x+y=-21\\3x+4x=-21\\7x=-21\\x=-21/7\\x=-3$

So, value of x = -3

Now, putting value of x into equation 1 and find value of y

$y=4x\\y=4(-3)\\y=-12$

Value of y = -12

So, value of x= -3 and value of y = -12

Solution set is (-3,-12)

The population of a certain community is known to increase at a rate proportional to the number of people present at time t. If

attashe74 [19]

Answer:

$t=7.85 years$

Step-by-step explanation:

We can write this rate as an ordinary differential equation.

$\frac{dP}{dt}=aP$

Where a is proportional constant, P the population variable, and t the time.

$\frac{dP}{P}=adt$

Integrating each side of the equation.

$\int \frac{dP}{P}=\int adt$

$ln(P)=at+c$

$P=e^{at+c}$

$P=e^{c}e^{at}=Ce^{at}$

To find C we need to use the initial condiction, it means evaluae P at t=0.

$P_{0}=Ce^{0}=C$

$P=P_{0}e^{at}$

Now, we use the sentence the population has doubled in 5 years.

$2P_{0}=P_{0}e^{a5}$

We can find "a" in this condition.

$2=e^{a5}$

$ln(2)=a5$

$a=\frac{ln(2)}{5}$

$a=0.14$

Finally, let's find how long will it take to triple.

$3P_{0}=P_{0}e^{0.14t}$

$3=e^{0.14t}$

$t=\frac{ln(3)}{0.14}$

$t=7.85 years$

I hope it helps you!

sdas [7]

Answer:

<h2>f(x) = 4</h2>

Step-by-step explanation:

f(x) = 2x

When x = 2

Substitute the value of x into f(x)

That's

f(2) = 2(2)

= 4

Charles has read 180 pages of a book this is 3/4 of the total number of pages in the book If P represents the number of pages in

KengaRu [80]

The answer is 240 :3

60+60= 120
120+60 = 180
and 60 more would be 240

60 fours would be 240
3 60's would be 180. So your answer is 240
