Divided by a positive number, not change

divided by a negative number, change sign

Example

10 > 5

divided by 5, no change in sign: 2 >1

but divided by -5, change sign: -2 < -1

If y varies directly with x and y=100 when x=5, what is the value of k?
horrorfan [7]
When it says varies directly, it means that y and x are going to be on opposite sides of the equals sign and that there is a constant, k,

y=kx

Plug in (5,100)

100=k(5)

K=20

???????????????????????????
IrinaVladis [17]
To find the scaled version of this rectangle by 1/2, start by identifying what this scale factor does to effect the numbers.

In this case, it causes each to divide by two.
Divide each value on the length and width of the rectangle by two.
This results in:
4/2
8/2

Now, perform the division to find your final answer.
This gives you 2 ft by 4 ft.

Answer choice C is the best option.

I hope this helps! :)
