Step-by-step explanation:
756 = 2² * 3³ * 7.
For 756n to be a perfect cube, all of its prime factors must have a power that is a multiple of 3.
How to get from 2² to 2³: Multiply by 2.
3³ has already a power that is a multiple of 3.
How to get from 7 to 7³: Multiply by 7².
Hence n = 2 * 7² = 98.
3x -1/2y = -7/2
x = -2y + 1
3 (-2y + 1) -1/2y = -7/2
-6y +3 -1/2y = -7/2
-13/2y = -13/2
y = 1
x = -2(1) + 1
x = -1
Answer = (-1, 1)

Answer:
D
Step-by-step explanation:
The line can be named with small latin letters or with two large latin letters which represent two points lying on the line.
Consider all options:
A. Points V and X lie on the line, so you can name the line as VX (true option)
B. Points W and X lie on the line, so you can name the line as WX (true option)
C. p represents the line (small letter given on the diagram) - (true option)
D. You cannot name the line using point V and line p, so this option is false
One month = 5000
Number of months before the spark plugs need to change :
15000 ÷ 5000 = 3
The sparks can last 3 months before it needs to be changed.
Number of times it need to change in a year = 12 ÷ 3 = 4
-----------------------------------------------------------------------------
Answer : It needs to be change 4 times a year.
