Answer: Y=-1/4x
Step-by-step explanation:
A good way to find an equation of a line is to look for the slope. An obvious spot on this line would be when it crosses (0,0), and another one to the right would be when it crosses at (4,-1).
The slope is rise over run, or if we use the two points we found, "rise" would be -1, because it's dropping 1 unit when going from (0,0) to (4,-1), and the "run" would be 4, because it moves to the right 4 from (0,0) to (4,-1).
Putting these two values together we get:
m (slope) = rise / run
m = -1 / 4
Out of all the equations we're given, we can look for the one with a slope of -1/4, which is given to us:
y = (-1/4)x
I believe it is numbers 184x√2
Answer:
923000.
Step-by-step explanation:
You want to find the number in which 9 represents 1/10th of its value in 92300. Naturally, this number would be 10 times larger. Multiply 92300 by 10 to get 923000.
Answer:
=64 %
Step-by-step explanation:
The percentage decrease is found by
Percent decrease = (original - new)/ original * 100 percent
The original price is 25
The new price is 9
Percent decrease = (25-9)/25 * 100%
=16/25 * 100%
=64 %
