Answer:
16) 
17) y = -x - 4
18) y = -2x - 1
19) y = -2x
20)
Step-by-step explanation:
With the two points you find the slope using 
Then using that slope, plug the slope in with one of the points values of x and y into the point slope formula, and smiplify that into the y-intercept formula.
<span>d. y = 15x 900</span>
Although you do not give the rates I assume the answer is D as it is the only positive multiplication. You cannot have negative height.
No, he is not correct. The lines are the same, so there are an infinite number of solutions.
When two lines are parallel, then the solution is empty set.
You are given 2cos² (4θ - 1). You are asked to s<span>implify the expression by using a double-angle formula.
Apply the double angle of the cosine function
</span>cos2θ = 2cos² θ - 1
Rearranging the expression and then substituting them
2cos² θ = cos2θ + 1
2cos² (4θ - 1) = cos 2(4θ - 1) + 1
cos2(4θ - 1) + 1
