Answer:
x = 73
General Formulas and Concepts:
- Order of Operations: BPEMDAS
Step-by-step explanation:
<u>Step 1: Define equation</u>
(180 - x) + (90 - x) = 124
<u>Step 2: Solve for </u><em><u>x</u></em>
- Combine like terms: 270 - 2x = 124
- Subtract 270 on both sides: -2x = -146
- Divide -2 on both sides: x = 73
<u>Step 3: Check</u>
<em>Plug in x to verify it's a solution.</em>
- Substitute: (180 - 73) + (90 - 73) = 124
- Subtract: 107 + 17 = 124
- Add: 124 = 124
y = -4x - 1
It is a linear function different from the constant function. Therefore, if the range is only one number, then the domain is only one number too.
Let's calculate it:
y = -25 → -4x - 1 = -25 |add 1 to both sides
-4x = -24 |divide both sides by (-4)
x = 6
Answer: The domain = {6}.
It’s Quadrant I. The Cosine and its reciprocal are positive in the first quadrant only.
Pi + e= 5.85987448205 or 5.86 if rounded
