Answer:
W'(27,45)
Step-by-step explanation:
First we must fnd the scale factor of the dilation and then multiply the coordinates of W(3,5) by the scale factor.
Let k be the scale factor of the dilation centered at the origin.
The mapping for a dilation by a scale factor k is
But we were given the coordinates of the image, which is
Q'(-27,36)
Comparing coordinates:
We could compare the first coordinates too and get the same result.
The image of W(3,5) is given by:
X 3
-- = --
8 7
Cross Multiply
7x = 24
Divide
x = 3.2485...
A
Answer:
13y-10
Step-by-step explanation:
Expand: -5(-y+2): 5y-10
Add similiar elements: 8y+5y=13y
=13y-10
Answer: Yeah its a rational number.
You can always draw a straight line between two points, so 2 points are always collinear.
However, coplanar means that the two points fall within the same plane. If you’re describing two different points from two different planes, they wouldn’t be collinear, but if they were on the same, they would be collinear.
We can conclude from this information that the answer is B.
Hope this helps!
