Paul and Seth know that one point on a line is (4,2) and the slope of the line is -5. Each student wrote a different equation relating x and y . Do the two equations represent the same line ? Construct a mathematical argument to support your answer .

Answers

Answer:

Step-by-step explanation:

Paul's equation,

Since the given line is passing through a point (4, 2) and slope = -5,

y = mx + b

2 = -5(4) + b

2 = -20 + b

b = 22

Therefore, equation of the line will be,

y = -5x + 22

Seth equation,

Slope of a line passing through two points (x, y) and (4, 2),

m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

-5 = [tex]\frac{y-2}{x-4}[/tex]

-5(x - 4) = y - 2

-5x + 20 = y - 2

y = -5x + 22

Therefore, both the equations represent the same line.

Find the measure of angle LMN
please help me!!

Answers

Its 125
It cant be 25 or 29 because the angle is clearly obtuse
And
Angle MPQ is the same as LMN
If you take 125 and subtract 50 from it (because you need to add 50 to 3x) you get 75
After that you need to divide 75 by 3 because 3 is multiplied by x
You should get 25
Therefore X=25
If X=25 then 5x is 125

Two pounds of cashews costs $19. Which table best represents y, the total cost of the cashew for x pounds?

Answers

Answer:
I believe the answer is A.

Explanation:
If you divide 19 by 2 to get the cost of each pound, you will get $9.5 per pound.
Multiply that by three and it will give you $28.50.
The only graph with $28.50 on it is the first one! Therefore, it is A!

You do the same thing with the 5 and 8. Just take those numbers and multiply them by 9.5.

The amount of time it takes a swimmer to swim a race is inversely proportional to the average speed of the swimmer. A swimmer finishes a race in 25 seconds with an average speed of 6 feet per second. Find the average speed of the swimmer if it takes 50 seconds to finish the race.

Answers

9514 1404 393

Answer:

  3 feet per second

Step-by-step explanation:

If the time is multiplied by 2, the inverse relationship tells you the speed is multiplied by 1/2.

  (1/2)(6 ft/s) = 3 ft/s

The swimmer's average speed is 3 ft/s.

4/6 + 1/3 please help i need to get my grade up qwq

Answers

Answer:  1

Explanation:

1/3 is the same as 2/6

Imagine cutting a cake into thirds, then cutting each piece in two parts, so you'll have 6 pieces total. If you shade one third of the cake, then this is the same as shading 2/6 of a cake. The diagram shows this below.

Therefore 4/6 + 1/3 is the same as 4/6 + 2/6

At this point, we add the numerators over the common denominator

4/6 + 2/6 = (4+2)/6 = 6/6 = 1

Meaning we get a full cake since 4/6 is four slices and 2/6 is another two slices leading to 4+2 = 6 slices total out of the 6 overall.

A tank contains 5,000 L of brine with 11 kg of dissolved salt. Pure water enters the tank at a rate of 50 L/min. The solution is kept thoroughly mixed and drains from the tank at the same rate. (a) How much salt is in the tank after t minutes? y = ___________kg (b) How much salt is in the tank after 20 minutes? () y = ________ kg

Answers

Answer:

a

  [tex]y(t) = 11e^{-\frac{t}{100} }[/tex]

b

  [tex]y(20) = 9 \ kg[/tex]

Step-by-step explanation:

From the question we are told that  

    The volume of brine in the tank is  [tex]V_L = 5000 \ L[/tex]

     The mass of the salt is [tex]y(0)= 11 \ kg[/tex]

     The rate at which water enters that tank is [tex]\r V = 50 \ L / min[/tex]

Generally the rate at which salt enters the tank is mathematically represented as

           [tex]z = \frac{0}{V_L} * \r V[/tex]

=>        [tex]z = \frac{0}{5000} * 50[/tex]

Here the zero implies that there is no salt entering the tank

Generally the rate at which salt leaves  the tank is mathematically represented as

           [tex]u = \frac{y(t)}{V_L} * \r V[/tex]

=>        [tex]u = \frac{y(t)}{5000} * 50[/tex]        

=>        [tex]u = \frac{y(t)}{100}[/tex]

Generally the rate of salt flow in and out of the tank is              

       [tex]\frac{dy}{dt} = z - u[/tex]

=>    [tex]\frac{dy}{dt} = - \frac{y(t)}{100}[/tex]

=>    [tex]\frac{dy}{y} = -\frac{dt}{100}[/tex]

=>    [tex]ln(y(t)) = -\frac{t}{100} + c[/tex]

at time  t = 0  y(0) =  11

=>  [tex]ln(11) = -\frac{0}{100} + c[/tex]

=>   [tex]c = ln (11)[/tex]

So

    [tex]ln(y(t)) = -\frac{t}{100} + ln (11)[/tex]

taking exponent of both sides

    [tex]y(t)=e^{ -\frac{t}{100} + ln (11)}[/tex]

=>  [tex]y(t) = e^{-\frac{t}{100} } * e^{ln(11)}[/tex]

=>  [tex]y(t) = 11e^{-\frac{t}{100} }[/tex]

Generally at t = 20 minutes

 The amount of salt in the tank is mathematically represented as

         [tex]y(20) = 11e^{-\frac{20 }{100} }[/tex]

=>      [tex]y(20) = 9 \ kg[/tex]

Multiplying and dividing fractions are essentially the same process which you multiply the numbers straight across and no need for common denominators. Except in division of fractions, the second fraction is flipped so that the denominator is on the top and the numerator is on the bottom (reciprocal).

Step-by-step explanation:

Example:

[tex]\frac{3}{4} * \frac{1}{5} = \frac{3}{20}[/tex]

[tex]\frac{3}{4}[/tex] ÷ [tex]\frac{1}{5} = \frac{3}{4} * \frac{5}{1} = \frac{15}{4}[/tex]
