Answer:
A' (6, -2)
B' (4, 2)
C' (10, 6)
Step-by-step explanation:
When you dilate by a scale factor of 2 about the origin, multiply each coordinate point by 2.
(3, -1) × 2 = (6, -2)
(2, 1) × 2 = (4, 2)
(5, 3) × 2 = (10, 6)
Answer:
Option A,$320.98 is correct
Step-by-step explanation:
The new balance on Elijah's credit is the sum of the last balance plus new charges minus payments made.
last balance as shown by the statement was $152.58
new charges were $213.40
payment made by Elijah was $45
new balance=$152.58+$213.40-$45=$320.98
The rationale for this is that the new charges on the card account add to previous balance owed by Elijah while the payment of $45 made reduces overall balance.
