X = (12/5,0)
y = (0,-4)
substitute 0 in for y & solve for x , to find the y-intercept substitute 0 in for x and then solve . ( I hope that makes sense)
Answer:this is the answer
Step-by-step explanation:
Two 12-Hour Periods The 12-hour system divides the 24 hours of a day into two periods lasting 12 hours each. The first 12-hour period is designated as am. It runs from midnight to noon. The second period, marked pm, covers the 12 hours from noon to midnight.
Answer:
Step-by-step explanation:
Go to Khan Academy and type in Solving linear systems the matrices (video).
Answer:
To prove that ( sin θ cos θ = cot θ ) is not a trigonometric identity.
Assume θ with a value and substitute with it.
Let θ = 45°
So, L.H.S = sin θ cos θ = sin 45° cos 45° = (1/√2) * (1/√2) = 1/2
R.H.S = cot θ = cot 45 = 1
So, L.H.S ≠ R.H.S
So, sin θ cos θ = cot θ is not a trigonometric identity.
Step-by-step explanation:
The given expression is :
....(1)
Taking LHS of the above expression

Rationalizing both denominator and numerator.

Equation (1) becomes,

Equating both sides,
and 
Hence, this is the required solution.
