Step-by-step explanation:
y is directly proportional to x
y = kx
k represents the constant of proportionality.
when y = 20 and x = 8:
20 = 8k
Dividing both sides by 8 gives:
k = 2.5
Hence when x = 3.
y = 2.5(3)
y = 7.5 .
Answer:
The slope of the line is 6.
Step-by-step explanation:
Two points on the line are (1,5) and (-1,-7)
y1 - y2 / x1 - x2
-7-5/-1-1 = -12/-2 = 6
A because the face are always going to be the same.
A square has 4 sides that are all the same length so 12.8 divided by 4 is 3.2 so each side 3.2 m
