Answer:
Where's the figure,my friend?
Answer:
2:35 pm
If an hour is 60 minutes, what we know is that 30 minutes is half. However, we must subtract 55 from 30 (In time)
To make this easier, subtract 55 by actual 30, and split 55 into 2 parts, the result of subtraction, and the other value, 30

Now, subtract.


If this is the case, the lesson must have started at 2:35 pm
Answer:
Perpendicular, 1
Step-by-step explanation:
Parallel means the same slope
Perpendicular is the reciprocal and opposite sign
25% decrease because if you multiply 20x.25 you get 5 and you minus the 5 from 20 books and you get 15 books
The value of k is 3
Solution:
Let us first find the equation of the line f(x).
The points on the line are (-6, -2) and (0, 4).
Here, 
Formula to find equation of a line:




Do cross multiplication.
y + 2 = x + 6
y = x + 4
f(x) = x + 4
Given that g(x) = f(kx)
g(x) = kx + 4
The point in the graph of g(x) is ( -2, -2).
g(-2) = k(-2) + 4
we know that g(-2) = -2.
-2 = -2k + 4
Subtract 4 from both sides.
-6 = -2k
Divide by -2 on both sides.
3 = k
k = 3
The value of k is 3.
