What is the solution of the system of equations 3x plus 6y and ndash2 15x plus 30y and ndash10?
Without any equality signs the given expressions can't be considered to be simultaneous equations and so therefore no solutions are possible.
What equation can come out of the direct variation that includes the point ( and ndash10 and ndash17).?
In direct variation, the relationship between two variables ( y ) and ( x ) can be expressed as ( y = kx ), where ( k ) is the constant of variation. Using the point (-10, -17), we can substitute these values into the equation: ( -17 = k(-10) ). Solving for ( k ) gives ( k = \frac{-17}{-10} = \frac{17}{10} ). Therefore, the equation representing the direct variation is ( y = \frac{17}{10}x ).

What happens to a glass of water at a temperature of 20 and degC when it is placed into a freezer set at and ndash10 and degC?
When a glass of water at 20°C is placed in a freezer set at -10°C, heat will transfer from the warmer water to the colder environment of the freezer. As the water loses heat, its temperature will drop, eventually reaching 0°C, where it will begin to freeze. The freezing process will continue until the water is fully converted to ice, assuming sufficient time is allowed for the temperature to stabilize.
