Answers:
Scale Factor = 3/4
This is a <u>reduction</u>
======================================================
Explanation:
Let's focus on the point R(4,4). That's the preimage point for the image of R ' (3,3).
Let k be the scale factor. We multiply this value of k by the x,y coordinates of point R to jump to R '
we have x = 4 jump to 4k which is the x coordinate of point R'
So we set 4k equal to 3 and solve for k to get k = 3/4. The scale factor is 3/4 or 0.75
We have a reduction since the image triangle T'R'S' is smaller compared to the preimage triangle TRS. We can see that we have a reduction by looking at the scale factor. If 0 < k < 1, then we have a reduction. If k > 1, then we have an enlargement instead. So we go with the first option since 0 < 3/4 < 1 or you could say 0 < 0.75 < 1.
Answer:
The answer is 7/20 miles.
Step-by-step explanation:
Just multiply 7/6 x 2/5, then you have the answer
Answer to 3 is 441
answer to 4 is 12.4 (using pythagorem theorem which is A squared plus B squared equals C squared)
7 / (x-3) = 1
(x-3) ((7 / (x-3)) = 1 (x-3) multiply both sides by (x-3), (x-3) on the left is cancelled
7 = x-3
3+7 = x - 3 + 3 add both sides by 3, 3 on the right is cancelled
x = 11
