Step-by-step explanation:

The break-even point is on both curves. The y-intercept can be used for the other point in each case.

The break-even point is where cost and revenue are the same:

  20/3x +50 = 10x

  50 = 10/3x . . . . . . . . subtract 20/3x

  15 = x . . . . . multiply by 3/10

  r = c = 10(15) = 150 . . . . for x = 10

Two points you can use for graphing the lines are ...

  cost: (0, 50) and (15, 150)

  revenue: (0, 0) and (15, 150)

The rise is 8 and run is 6

Answer:

The answer is J) y=-4/3x+8

AC=37

BC=5X+6

AB=2X + 3

2x + 3 + 5x + 6 = 37

7x + 9 = 37

7x = 28

x = 4

BC = 5(4) + 6

BC = 26

Answer = BC = 26

Answer:

Step-by-step explanation:

sin(x) + tan(x) =sin(X) + sin(x)/cos(x)

=sinx(1+1/cosx)

=Sinx(1+secx)

=1+secx/cosecx. (Since sinx=1/cosecx)

Hence LHS=RHS proved

Answer:

C.  x=2.5, DC=7.5, EC=15

Step-by-step explanation:

since the triangles have congruent angles, the sides have a relationship too. Basically, the ratio between the triangle is 4:10 because those sides math up. So, that also means it is 2:5. Therefore, BC:EC=6:15. 15-12.5=2.5, so x=2.5.

Now you can just do 2.5+5=7.5 so DC=7.5

Answer:

120 minutes or 2 hours I think

Step-by-step explanation:

ok so you want to figure out how many hours it will take for her to bake 48 cookies. It takes 15 minutes to bake 6 cookies.

So 6x8=48 cookies.

Multiply 15 minutes times 8 since one batch of cookies (6) 15 minutes long and she wants to bake 48 cookies.

15x8=120

That's 120 minutes, but you want how many HOURS it takes.

there are 60 minutes on a hour so you will take 120 divided by 60

120/60= 2

To check, multiply 60x2= 120.

Hope this helps!

Answer:

x = 5

Step-by-step explanation:

Here, from what we have, the angle and the sides facing it are equal

Since we have pi oh both sides

Thus;

6x + 6 = 9x-9

9x-6x = 9 + 6

3x = 15

x = 15/3

x = 5

4-3    

4-1 =  1/3

y=1/3x

Answer:

y=2/3x-16/3    

Step-by-step explanation:

ok ill show you how to do one question since the rest will take too long so what you do is

equation is y=mx+b right

so you have slope and these points (2,-4) and m=2/3

y=2/3x +b right

now all you do is sub in x and y which are ur given points

-4=2/3 (2) +b

now you solve for b

-4 = 4/3 + b

-4-4/3 = b

-12/3 - 4/3 = b

-16/3=b so therefore

y=2/3x-16/3

Step-by-step explanation:

This might have been helpful to Newton as it allowed him to focus more clearly on his ideas. Newton was incredibly talented and ahead of his time in his field, which being in isolation helped him focus and develop on his ideas. This is not the case for the majority, most scientists tend to focus on a single aspect of a problem, usually the aspect that they have the most experience in. This can lead to them being blinded and not being able to see the possible solution. That is why working with others that are able to view the problem from a different perspective can help greatly.

Working in isolation might have helped Newton focus clearly on his ideas.

Working in isolation might be problematic in developing scientific ideas because of the tendency of having a narrow perspective about a problem and not being able to find possible solution.

Working in isolation means to work remotely or alone without the input or help from other people.

Working in isolation might have been helpful to Newton, who was quite talented, as it may have enabled him focus clearly on his ideas.

1. Tendency of having a narrow perspective about a problem.

2. Probability of not being able to find possible solution.

In summary, working in isolation might have helped Newton focus clearly on his ideas.

Answer:

(1 + 2i)(1 - 2i)

Step-by-step explanation:

Multiplying a complex number and its conjugate results in a real number.

Thus

1 + 2i and 1 - 2i are conjugates

(1 + 2i)(1 - 2i) ← expand using FOIL

= 1 - 2I + 2I - 4I² [ note i² = - 1 ]

= 1 - 4(- 1)

= 1 + 4

= 5 ← a real number

The sum of the two solutions to the given equation is 1/3.

Step-by-step explanation:

Nature of Roots of a Second-Degree Equation

Given a quadratic equation:

[tex]ax^2 + bx + c = 0[/tex]

The roots of the equation are:

[tex]\displaystyle x_1=\frac{-b+ \sqrt{b^2-4ac}}{2a}[/tex]

[tex]\displaystyle x_2=\frac{-b- \sqrt{b^2-4ac}}{2a}[/tex]

The sum of the roots is:

[tex]\displaystyle x_1+x_2=-\frac{b}{a}[/tex]

The sum of the roots of a quadratic equation is equal to the negation of the coefficient of the second term, divided by the leading coefficient.

We are given the equation:

[tex]3x^2 - x = 4[/tex]

Rearranging:

[tex]3x^2 - x - 4=0[/tex]

The coefficient b is b=-1, and the leading coefficient is a=3, thus the sum of the roots is:

[tex]\displaystyle x_1+x_2=-\frac{-1}{3}[/tex]

[tex]\displaystyle x_1+x_2=\frac{1}{3}[/tex]

The sum of the two solutions to the given equation is 1/3.
