HELLOO HELPPP PLS I NEDD ON 2,3
1 answer:
For number 2, you set up a proportion, which in this case, is 17/1 = w/6.
To get w by itself you need to get rid of the 6 in the denominator by canceling it out buy multiplying by the reciprocal.
Your new equation should be 6/1 = 17/1 or 17.
You then multiply 6 and 17 to get a total of 102
Hope this helps!

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>
