Applying a dilation centered at the origin with scale factor
has the effect of multiplying both coordinates of a point by
:

So, in your case, the coordinates of the points double:

Answer:
Simplify the expression.
t^/9
Step-by-step explanation:
17) 146 min.
18) 5 hrs and 31 min
19) -1/6
Answer:

Step-by-step explanation:
The given equation is:

To find the point where this line intersect the y-axis, we put x=0 into the given equation.
When x=0, we have
.
This implies that; y=5.
The y-intercept is (0,5).
Comparing (0,5) to (0,b), we can conclude that; b=5
