Three planes that intersect in a point?
The intersection of three planes is either a point, a line, or there is no intersection if any two of the planes are parallel to each other. This tells us about possible solutions to 3 equations in 3 unknowns. There may be one solution, no solution, or infinite number of solutions.
How can you tell if a system of equations has no solution?
Assuming that the system is two linear equations of two unknowns, solving by substitution will produce a constant that is equal to a different constant. This is because each equation defines a line and the only way for there to be no intersecting points between the two lines would be for them to be parallel to each other. So that their y=mX+b forms will only differ by their y-intercepts since their slopes will be identical. Setting the mx+b portion of the two equations equal to each other allows us to subtract mx from each side of the equal sign leaving us with the slope intercepts being equal to each other. BUT since the y-intercepts were different, we will arrive at a contradiction. By the way, solving a system of linear equations and having it produce a constant being equal to itself means that the two lines coincide and have infinitely many solutions.
What is the definition of the math term properties?
variables that allows us to preform equations with numbers.
What are units of the US system of measurement called?
US system, or imperial system.
How do quadratic equations help us in your daily life?
Quadratic equations doesn't help you in life specifically. It just combines a bunch of different math properties. It helps to focus your brain, gain concentration and intellect.
What do the numbers in the intersection have in common?
This is very difficult to answer correctly if you don't tell us what the numbers in the intersection are.
What equations tell us how fast a wave travels?
Speed of light/wavelength = wave frequency

What does the age of the lunar rocks tell us about our solar system?
They tell us the age of the moon, which indicates when the Solar System itself was being formed.
What are the advantages of using symbols instead of words?
Symbol equations generally provide more information than word equations, and can be used to calculate things such as energy gain/loss or theoretical yield.Word equations only tell us what the reactants and the products are, whereas symbol equations tell us which and how much of each element is present in the chemicals (their names may not always reflect this) and may give some indication as to their structure, which determines their chemistry. Also, symbol equations are balanced, which gives a clear indication as to how much of one set of things makes the other.
What is the Quota system in the Police Department like?
In the US - they will tell you that there is no 'quota' system.
A sentence for intersection?

What system can tell us that an earthquake is coming?
seismograph is how to measure the intensity the earthquake will be or was.
What does the age of the rocks tell us about your solar systems?
How the solar system made
What do observations of stellar explosions and nebulae tell us?
it is how the solar system started
What are the positive and negative effects of the Hubble space telescope?
The positive effects are:- It can show us deeper into the solar system and tell/show us more about each planet It can increase our knowledge about the universe The only negative so far is that:- It might lose pieces about break down It can show us deeper into the solar system and tell/showIt can show us deeper into the solar system and tell/show us more about each planet us more about each planet
