Answer:

x = a + b

Step-by-step explanation:

This is a proof

Exterior angle of a triangle = Sum of Interior and opposite angles

Exterior angle of a triangle = x

Sum of Interior and opposite angles = a + b

know that

a + b + c = 180       ______1          (total sum of angles in a triangle)

x + c = 180   _______2                 (total sum of angles on a straight line)

from equation 1

c = 180 - (a + b)

from equation 2

c = 180 - x

hence

180 - (a + b) = 180 - x

180 - 180 + x = a + b

x = a + b

Select steps that could be used to solve the equation 1 + 3x = -x + 4.
Olegator [25]

Answer:

A, C & D

Step-by-step explanation:

A) 1 + 3x = -x + 4  {subtract 1}

  1 + 3x -1 = -x + 4 - 1

       3x     = -x + 3         {add x}

     3x + x = -x + 3 + x

        4x    = 3       {Divide by 4}

       4x/x = 3/4

x = 3/4

C) 1 + 3x = -x +4            {Add x}

  1+ 3x + x = - x +4 + x      

   1 + 4x  = 4    {subtract 1}

        4x = 4 - 1

        4x = 3   {Divide by 4}

D) 1 + 3x = -x + 4        { Subtract 3x}

         1    = -x + 4 -3x

         1 = -4x + 4          Subtract 4}

      1 - 4 = -4x

        -3 = -4x              {Divide by -4}

       -3/-4 = x

x = 3/4  

          x = 3/4

Whenever you sign a lease for an apartment, you typically have to pay a security deposit before you even move in; this is in cas
likoan [24]
The answer is F(x) = 900x + 600

Let x stands for the number of months

The apartment is rented for $900 a month, so every month it will be paid 900x (for example, for one month (x = 1), you will pay 900 · 1 = $900, for three months (x = 5), you will pay 900 · 5 = $4500, etc.)

A security deposit is paid only once and is not dependent on the number of months. So, its value is only 600. 

These two values must be summed up because both must be paid, nothing is to subtract. Therefore, the function f(x) for  apartments that rent for $900 a month and a security deposit of $600 is:
f(x) = 900x + 600

Write the function for the following chart,
timurjin [86]
Dy/dx=1/2, 1/2, 1/2 etc

So this is a linear equation of the form y=mx+b where m=dy/dx=1/2 so

y=x/2 +b, now we can use any point to solve for the y-intercept, "b", I'll use (7,0)

0=7/2 +b

b=-7/2 so

y=x/2-7/2

y=(x-7)/2

Divide (18x^3 + 12x – 3x) ÷ 6x^2
andre [41]
First let's simplify it

\frac{18x^3 + 9x}{6x^2}

Now let's factor it
\frac{9x(2x^2 + 1)}{6x^2}

Lastly, let's simplify
\frac{3(2x^2 + 1)}{2x}
