Answer:
(2,-1)
Step-by-step explanation:
Multiply first equation by 2:
10x + 2y = 18
Subtract the second equation from this so that the 2y terms cancel:
10x - 3x = 18 - 4
7x = 14
x = 2
Plug into first equation to find y:
5(2) + y = 9
10 + y = 9
y = -1
The answer is (2,-1)
Rotating Q 180 degrees using the center P has the same effect as reflecting Q over the Line M
Step-by-step explanation:
Rotating Q 180 degrees using the center P has the same effect as reflecting Q over the Line M and this is because Lines L and M are perpendicular lines ( i.e. lines that meet a right angle ( 90° ).
Hence rotating Q 180 degrees form the center will be similar to reflecting Q over any of the perpendicular lines

Answer: 1320
Step-by-step explanation:
Given,
HCF of two numbers = 40
Product of two numbers = 52800
To find,
LCM of two numbers =?
Formula required,
HCF × LCM = product of two numbers
Calculation,
Using formula
→ HCF × LCM = product of two numbers
→ ( 40 ) × LCM = 52800
→ LCM = 52800 / 40
→ LCM = 1320
Therefore,
LCM of two numbers would be 1320.
