Find the equation parallel to y = -x - 5 and passing through (-3, -3)

qwelly [4]

Answer:

y = -x - 6

Step-by-step explanation:

If it's parallel, then it means that the slope will remain the same. The slope is

-1.

To find the y-intercept, you need to plug the coordinates into the equation,

y = -1x + b

-3 = -1(-3) + b

-3 = 3 +b

-6 = b

The equation is y = -x - 6

Will Mark The Brainliest. Write an equation of the line graphed in slope-intercept form using the variables x and y.

baherus [9]

Answer:

$\boxed{y=-2x+5}$

Step-by-step explanation:

The equation in slope-intercept form is given by:

$y=mx+c$

where $m$ is the slope and $c$ is the y-intercept.

The given line passes through so many points. We can use any two these points to find the slope of the line.

The line passes through $(x_1,y_1)= (1,3)$ and $(x_2,y_2)=(2,1)$ .

The slope is given by;

$m=\frac{y_2-y_1}{x_2-x_1}$ .

$\Rightarrow m=\frac{1-3}{2-1}$ .

$\Rightarrow m=\frac{-2}{1}=-2$ .

The y-intercept from the graph is $c=5$

Our equation finally becomes;

$y=-2x+5$

The rate of change (dP/dt), of the number of people on an ocean beach is modeled by a logistic differential equation. The maximu

Kazeer [188]

Answer:

$\frac{dP}{dt} = 2.4P(1 - \frac{P}{1200})$

Step-by-step explanation:

The logistic differential equation is as follows:

$\frac{dP}{dt} = rP(1 - \frac{P}{K})$

In this problem, we have that:

$K = 1200$ , which is the carring capacity of the population, that is, the maximum number of people allowed on the beach.

At 10 A.M., the number of people on the beach is 200 and is increasing at the rate of 400 per hour.

This means that $\frac{dP}{dt} = 400$ when $P = 200$ . With this, we can find r, that is, the growth rate,

$\frac{dP}{dt} = rP(1 - \frac{P}{K})$

$400 = 200r(1 - \frac{200}{1200})$

$166.67r = 400$

$r = 2.4$

So the differential equation is:

$\frac{dP}{dt} = rP(1 - \frac{P}{K})$

$\frac{dP}{dt} = 2.4P(1 - \frac{P}{1200})$
