The +3 is the vertical and the +5 tells you horizontal. so this graph moves 3 up and 5 left. But since it only wants vertical that would be the +3
Answer:
(a) 
(b)300 Hours
(c)150 Hours
(d)Reduced and halved.
(e) 
Step-by-step explanation:
(a) The number of hours worked is inversely proportional to the wage.
This is written as:

(b)If the student earns $8 an hour
w=$8

(c)When the wage per hour =$16
When w=$16

The number of hours reduced and is in fact halved.
(d)

The effect of raising the wage from $w to $2w per hour is that the number of hours required to work is reduced and exactly halved.
(e)The wage per hour is inversely proportional to the number of hours.
In fact,

When you factor (x^2-4x-5), you get (x+1)(x-5).
Answer:
C=30
Step-by-step explanation:
Supposing that we have the lines
x+2=10y
and
3x+6=Yc.
Note that dividing by 3 the second line can be rewritten as
x + 2= Y c/3.
Remember that a line is written as
, in our case, both lines have
and
. Therefore, in orther that the two lines are equal, we need that
, hence
