<span>If a quantity increases by 25% and then decreases by 25%, will that result be the original quantity? Explain.
Let’s try to be able to know the answer:
=> Let’s have 10 as the value
Increase by 25%
=> 10 + 25%
=> 10 * .25 = 2.5
=> 10 + 2.5 = 12.5 the new value
Now, decrease this by 25%
=> 12.5 – 25%
=> 12.5 * .25 = 3.125
=> 12.5 – 3.125 = 9.375 or 9.4
Thus, the given statement is false.

What would the y intercept of a line B if it is perpendicular to 1/3x+2

Thepotemich [5.8K]

Hey!

Hope this Helps....

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

To find the perpendicular line, of any given line goes like this...

if m (slope) of this given line is 1/3, than we know that the perpendicular line has a slope of -3

Now, to find the equation of this line, we need to find out where it crosses the y-axis... And because we are not given any specific points on where the perpendicular line crosses. We see that the point it pass the y-axis is 0

So... the perpendicular line of 1/3x+2 is -3x
