Answer:
The answer is C
Step-by-step explanation:
<em>(i-j) - (2i - 3j) = -i - 4j</em>
Answer:
99
Step-by-step explanation:
Answer:
(x -1)(x -5)
Step-by-step explanation:
We recognize that 6 is the sum of the factors of 1·5, so we can write the factorization as ...
x^2 -6x +5 = (x -1)(x -5)
_____
The product of factors will be ...
(x +a)(x +b) = x^2 +(a+b)x +ab
So, the binomial constants "a" and "b" are factors of the trinomial constant that have a sum equal to the coefficient of the linear term. Here, those are factors of +5 that have a sum of -6. The factors of interest are -1 and -5: 5 = (-1)(-5); -6 = (-1) +(-5).
So..hmm notice the picture below
all those are reference angles, of the bigger orange one
a reference angle, is just the angle the terminal point makes, with the x-axis
that angle, is called a reference angle, because, is an equivalent x,y value
