Answer:
p = 23 and p = -22
Step-by-step explanation:
| 2p -1 | =45
Absolute value equations have 2 solutions, one positive value and one negative
2p-1 = 45 and 2p-1 = -45
Add 1 to all sides
2p-1+1 = 45+1 and 2p-1+1 = -45+1
2p = 46 2p = -44
Divide by 2
2p/2 = 46/2 and 2p/2 = -44/2
p = 23 and p = -22
The length of ND = 3 units
The length of N'D' = 6
6 / 3 = 2
The scale factor is 2
Answer:
Step-by-step explanation:
7+4y=7-5y+54
Collecting like terms
4y + 5y = 7 - 7 + 54
9y = 54
y = 54/9
y = 6
