Choice D
The slopes of two perpendicular lines are negative reciprocals of each other.
That would be five (5) correct?
4x-2=18
4x=20
x=5
The correct answer is all real numbers except y = 1.
There are two ways of finding this. The first way is by looking at the graph for a value which y never equals. If you look, there are no places where either part of the graph hits y = 1.
The second way is by looking at the combined equation.
(fog)(x) =
We know that , no matter what we put in can ever equal 0. Since that is true, we know y can never equal the number for when that equals 0. So plug in 0 and see what the asymptote is.
(fog)(x) = 0 + 1
(fog)(x) = 1
Therefore, y = 1 is the answer.
8.125 can be written as 65/8. 3.25 can be written as 13/4. 65/8 divided by 13/4 can be written as 65/8 x 4/13. 65 x 4 = 260. 8 x 13 = 104. 260/104 = 65/26 = 2.5
First question:
Reduce the ratio
150 ml
------------
0.3 l
Do this by use of the appropriate conversion factor:
150 ml 1 liter 150 liter
------------ * ------------ = ------------- = 0.5 liter.
0.3 l 1000 ml 300
Darren drinks more milk: 0.5 liter versus Randy's 0.3 liter.
