Answer:
The image of the point (1, -2) under a dilation of 3 is (3, -6).
Step-by-step explanation:
Correct statement is:
<em>What are the coordinates of the image of the point (1, -2) under a dilation of 3 with the origin.</em>
From Linear Algebra we get that dilation of a point with respect to another point is represented by:
(Eq. 1)
Where:
- Reference point with respect to origin, dimensionless.
- Original point with respect to origin, dimensionless.
- Dilation factor, dimensionless.
If we know that 
, 
and 
, then the coordinates of the image of the original point is:
![\vec P' = (0,0) +3\cdot [(1,-2)-(0,0)]](https://tex.z-dn.net/?f=%5Cvec%20P%27%20%3D%20%280%2C0%29%20%2B3%5Ccdot%20%5B%281%2C-2%29-%280%2C0%29%5D)
The image of the point (1, -2) under a dilation of 3 is (3, -6).
Answer:
Tammy is incorrect
Step-by-step explanation:
The product of 5/7 and 1 1/4 is,
(5/7) x (1 1/4)
turn the mixed number to a whole number.
1 1/4= 4/4 + 1/4 = 5/4
(5/7) x (5/4) = 25/28 which is approximately 0.8929
Tammy believes it equals 1 3/4
1 3/4 = 4/4 + 3/4 = 7/4 which is 1.75
0.8929 does not equal 1.75
