Answer:
The image is (-18,0)
Step-by-step explanation:
Here, we want to find the image of the given point after dilation by the given scale factor
Mathematically, given a point with the pre-image (x,y) going under the dilation of scale factor k, centered at the origin, the coordinates of the image will be;
(kx , ky)
Applying this in the given scenario, we have
(2(-9) , 2(0))
= (-18,0)
Step-by-step explanation:
a−(6a−(5a−8))
a-(6a-5a+8)
a-6a+5a-8
6a-6a-8
0-8
=-8
so the answer doesn't depend on a
what what what what what what what what what
In that situation, you use the information you DO have. It's not always
enough to do the job. But often it is, and in that case, you use what you
do have to answer the question or solve the problem.
Sadly, I can't be any more specific than that. You haven't told us what
information you do have ... only what information you don't have.
