Answer:
The answer to your question is:
Step-by-step explanation:
y = -3x + 16/3
Find y-intercept
To find it, x = 0
y = -3(0) + 16/3
y = 0 + 16/3
y = 16/3 ≈ 5.3 The point is (0, 16/3)
Find x-intercept
y = 0
0 = -3x + 16/3
-16/3 = -3x
x = -16/3/-3
x = 16/9 ≈ 1.8 The point is (1.8, 0)
We look for these points in the axis and finally join them.
Answer:
Given the expression:
1.
we know:
then;
Therefore, the value of expression is -16 i.e negative.
2.
we know:
then;
Therefore, the expression is 16 i.e Positive.
3.
we know:
then;
Therefore, the expression is 16 i.e Positive.
Answer:
Identity (a) can be re-written as
which we already proven in another question, while for idenity (b)
step A is simply expressing each function in terms of sine and cosine.
step B is adding the terms on the LHS while multiplying the one on RHS.
step C is replacing the term on the numerator with the equivalent from the pithagorean identity
