Find an equation for the inverse of the following relation.<br><br> y=12x-3
vovikov84 [41]
<h3>Answer:</h3>

<em>Your answer would be y=x+3/12</em>

<h3>Step-by-step explanation:</h3>

Firstly, you'll switch sides of the equation.

<em>y=12x+3 ---> x=12y-3</em>

Next, add 3 to both sides.

<em>x=12y-3 ---> 12y-3+3=x+3</em>

Simplify it.

<em>12y-3+3=x+3 ---> 12y=x+3</em>

Then, divide both sides by 12.

<em>12y=x+3 ---> 12y/12 = x/12 + 3/12</em>

Simplify once more.

12y/12 = x/12 + 3/12 --- y= x+3/12

<u>y=x+3/12 would be your answer.</u>

Given the following triangle, if c = square root of 7 and a = 1, find the measure of B.
Darya [45]

Answer:

  68°

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you that the relation between the angle's adjacent side and the hypotenuse is ...

  Cos = Adjacent/Hypotenuse

This means ...

  cos(B) = a/c

  B = arccos(1/√7) ≈ 68°
