Answer:
<h2><u>
(0,0)</u></h2><h2><u>
(4,9)</u></h2><h2><u>
(-1,5)</u></h2><h2><u>
(-4,-8)</u></h2>
Step-by-step explanation:
When an inequality is graphed, the solutions will be shaded in a color. \
On this graph, it is shaded blue.
First we want to put all the points on the graph. During this step, it does not mater if the point is in the blue or not.
Now that we have all 8 points plotted, we can begin elimination.
For this step, we will cross out or eliminate any points in the white.
Any points in the blue, will be correct
After doing this step, you should have the answers <u>(0,0), (4,9), (-1,5), (-4,-8)</u>
So those are the correct answers
General Idea:
When we are given a point P(x, y) centered at origin with a scale factor of k, then the dilated point will be given by P' (kx, ky)
Applying the concept:
In the diagram given, the coordinate of C is (6, 3). Triangle ABC is being dilated with the center of dilation at the origin. The image of C, point C' has coordinates of (7.2, 3.6).
If C (x, y) centered at origin with a scale factor of k, then the dilated point will be given by C' (kx, ky)
We know &
Substituting 6 for x in the equation , we get .
Dividing 6 on both sides
Simplifying fractions on both sides
Point A from the diagram is (-3, 3)
x-coordinate of A' =
y-coordinate of A' =
Point A' is given by (-3.6, 3.6)
Conclusion:
<u>Scale factor of dilation is 1.2</u>
<u>The coordinates of point A' is (-3.6, 3.6)</u>
$7 was paid to park the car for 3 hours.
3 hours cost $7 to park
1 hour = $ (7/3)
So every 1 hour cost $(7/3)
Therefore cost in dollars, c = (7/3)*p
Therefore c = (7/3)p, where c is the cost in dollars of parking and p is the number of hours.
