Mathematics

Answer:

Simplifying

(-4x + -2) + -1(13x + 1) = 0

Reorder the terms:

(-2 + -4x) + -1(13x + 1) = 0

Remove parenthesis around (-2 + -4x)

-2 + -4x + -1(13x + 1) = 0

Reorder the terms:

-2 + -4x + -1(1 + 13x) = 0

-2 + -4x + (1 * -1 + 13x * -1) = 0

-2 + -4x + (-1 + -13x) = 0

Reorder the terms:

-2 + -1 + -4x + -13x = 0

Combine like terms: -2 + -1 = -3

-3 + -4x + -13x = 0

Combine like terms: -4x + -13x = -17x

-3 + -17x = 0

Solving

-3 + -17x = 0

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '3' to each side of the equation.

-3 + 3 + -17x = 0 + 3

Combine like terms: -3 + 3 = 0

0 + -17x = 0 + 3

-17x = 0 + 3

Combine like terms: 0 + 3 = 3

-17x = 3

Divide each side by '-17'.

x = -0.1764705882

Simplifying

x = -0.1764705882

Answer:

x = -3/17

Step-by-step explanation:

<u>Step 1:  Distribute the minus sign</u>

(-4x - 2) - (13x + 1)

-4x - 2 - 13x - 1

<u>Step 2:  Combine like terms</u>

-4x - 2 - 13x - 1

-17x - 3

<u>Step 3:  Solve for x</u>

-17x - 3 = 0

-17x - 3 + 3 = 0 + 3

-17x / -17 = 3 / -17

x = -3/17

Answer:  x = -3/17

Which double-angle or half-angle identity would you use to verify that 1+cos2a=2/1+tan2a?
juin [17]

In this case or scenario, the double-angle identity that should be used is the one for cosine. <span>

In totality, we shall need the following three trigonometric identities to end up with the equality: 

<span>1. cos (2a) = cos² (a) - sin² (a)
2. sin² (a) + cos² (a) = 1 
<span>3.  tan² (a) + 1 = sec² (a)

<span>Using identities 1 and 2 on the left-hand side of the equation, we get the following:</span>

1 + cos (2a) = 1 + cos² (a) - sin² (a) = 2 cos² (a) </span></span></span>

<span>

<span>Recalling that cos² (a) = 1 / sec² (a) and applying identity 3, we find the following:</span>

2 cos² (a) = 2 / sec² (a) = 2 / (1 + tan² (a)) </span>

 

Therefore giving us:

<span>2 cos² (a) = 2 / (1 + tan² (a))</span>

What is the answer to this
olasank [31]

Three times the variable m minus four is equal to fourteen.

Another way could be:

Four less than three multiplied by m is equivalent to fourteen.


The first way I put it is simpler but if you really want to impress your teacher then I suggest going with the second way.

Also if you are looking to solve the equation then it would be:

3m - 4 = 14

      +4   +4

     ------------

       3m = 18

      -----    -----

         3        3

m = 5


Hope that helped :-)
