we have

y\leq \frac{1}{4}x+3 ----> inequality 1

The solution of the inequality 1 is the shaded area below the solid red line

The solution is the region D and region C

y\geq-x+5 -----> inequality 2

The solution of the inequality 2 is the shaded area above the solid blue line

The solution is the region B and region C

The solution of the system is the common area

so

The solution is the region C

see the attached figure

therefore

the answer is the option C

Answer:

Region C of  the graph will contains the solution to the given system

Step-by-step explanation:

 Consider the given system of equation

y\le\frac{1}{4}x+3

and y\ge-x+5

We have to choose the region of the graph that contains the solution to the given system.

Since, to determine the region choose  a test point in each region and then then check the values of inequality at that point and for the test point that satisfies both the inequality  will contains the solution to the given system.

On region A)

Let (0, 4)  be the test point that lies in region A

Then put the value of x = 0 and y= 4 in given system,

we have,

4\le\frac{1}{4}(0)+3 \Rightarrow 4\le 3 (false)

and 4\ge(0)+5 \Rightarrow 4\ge 5 (false)

On region B)

Let (0, 8)  be the test point that lies in region B

Then put the value of x = 0 and y= 8 in given system,

we have,

8\le\frac{1}{4}(0)+3 \Rightarrow 8\le 3 (false)

and 8\ge(0)+5 \Rightarrow 8\ge 5 (true)

On region C)

Let (8,0)  be the test point that lies in region C

Then put the value of x = 8 and y= 0 in given system,

we have,

0\le\frac{1}{4}(8)+3 \Rightarrow 0\le 5 (true)

and 0\ge(-8)+5 \Rightarrow 0\ge -3 (true)

On region D)

Let (0,0)  be the test point that lies in region D

Then put the value of x = 0 and y= 0 in given system,

we have,

0\le\frac{1}{4}(0)+3 \Rightarrow 0\le 3 (false)

and 0\ge(0)+5 \Rightarrow 0\ge 5 (false)

Thus, only (8,0)  be the test point that lies in region C satisfies both inequality.

Thus, region C of  the graph will contains the solution to the given system

Allisa [31]

Answer: If you are looking for Slope-Intercept form (y=mx+b), It would be...

y=-5.4x+10840.4.

If you are looking for Point-Slope form, it would be...

y=-5.4x+10840.4.

Step-by-step explanation: Write in Slope-Intercept from, y=mx+b.

Point-Slope form : Use the Point-Slope formula, y-y1=m(x-x1) to find the equation of the line.

I hope this helps you out! ☺

Suppose a tank contains 400 gallons of salt water. If pure water flows into the tank at the rate of 7 gallons per minute and the
Strike441 [17]

Answer:

Step-by-step explanation:

This is a differential equation problem most easily solved with an exponential decay equation of the form

y=Ce^{kt}. We know that the initial amount of salt in the tank is 28 pounds, so

C = 28. Now we just need to find k.

The concentration of salt changes as the pure water flows in and the salt water flows out. So the change in concentration, where y is the concentration of salt in the tank, is \frac{dy}{dt}. Thus, the change in the concentration of salt is found in

\frac{dy}{dt}= inflow of salt - outflow of salt

Pure water, what is flowing into the tank, has no salt in it at all; and since we don't know how much salt is leaving (our unknown, basically), the outflow at 3 gal/min is 3 times the amount of salt leaving out of the 400 gallons of salt water at time t:

3(\frac{y}{400})

Therefore,

\frac{dy}{dt}=0-3(\frac{y}{400}) or just

\frac{dy}{dt}=-\frac{3y}{400} and in terms of time,

-\frac{3t}{400}

Thus, our equation is

y=28e^{-\frac{3t}{400} and filling in 16 for the number of minutes in t:

y = 24.834 pounds of salt
