Crystal measures the mass of a beaker containing ice cubes and finds that its mass is 130 g. After an hour, the ice cubes have melted, and Crystal decides to take another measurement. What will be the mass of the beaker and the water?

130g

Step-by-step explanation:

Change of state from Solid to liquid doesn't affect the mass of the crystals.

The mass remains the same

what is the question here

step-by-step explanation:

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
