The reciprocal cosine function is secant: sec(theta)=1/cos(theta). The reciprocal sine function is cosecant, csc(theta)=1/sin(theta). The reciprocal tan function is cotan
Cotx=1\tanx
Multiply both sides by (3*5)
5(2n)=3(n+14)
distribute
10n=3n+42
minus 3n both sides
7n=42
divide both sides by 7
n=6
The two angles are supplementary angles and when added together equal 180 degrees.
3x -12 + x+2 = 180
Simplify:
4x -10 = 180
Add 10 to both sides
4x = 190
Divide both sides by 4
X = 190/4
X = 47.5
Answer:
x = 9
Step-by-step explanation:
Step 1: Write equation
-4 - x = -13
Step 2: Solve for <em>x</em>
<u>Add 4 to both sides:</u> -x = -9
<u>Divide both sides by -1:</u> x = 9
Step 3: Check
<em>Plug in x to verify if it's a solution.</em>
-4 - 9 = -13
-13 = -13
Answer:
'x' and 'y' have a positive association between them.
Step-by-step explanation:
We can see in the given data that as 'x' remains constant or increases by 1 unit, or two units in it's two consecutive values, in each of the cases 'y' increases by 1 unit.
Hence, 'x' and 'y' have a positive association between them.
