Answer:
(x+1)(2x+5)
Step-by-step explanation:
Answer:
B'(- 2, 2 )
Step-by-step explanation:
Assuming the dilatation is centred at the origin, then multiply the coordinates of B by the scale factor 2, that is
B(- 1, 1 ) → B'(2(- 1), 2(1) ) → B'(- 2, 2 )
49,000 is the nearest round to the hundredth to 48,950
Answer:
c
Step-by-step explanation:
7:3=28:12
Answer:

Step-by-step explanation:
Given
See attachment for ABCD and A'B'C'D'
Required
Determine the dilation rule
Using AB and A'B' as points of references;


The dilation factor (k) is calculated as:

This gives:

Factorize


Hence, the scale factor is 2.5
The dilation rule is:
