The domain of a function is the set of all values x can have.
From the graph, we see the least value of x is 3. x can be any value greater than or equal to 3.
The domain is
A gamma ray by definition, has a zero charge and a zero mass.
So when it is released it does not change the mass or nuclear charge of the parent material.
But it does involve the release of energy like all radioactive processes.
So the statement is True.
(- 3/4) + (-3/8)
= (- 6/8) - 3/8
= negative 9/8
To check the answer, sub in 67 for x and 25 for y in both equations...because for it to be a solution, it has to satisfy both of the equations.
(67,25)...x = 67 and y = 25
x + y = 92
67 + 25 = 92
92 = 92 (correct)
y = 3x - 4
25 = 3(67) - 4
25 = 201 - 4
25 = 197 (incorrect)
so (67,25) is NOT a solution to this system of equations because it does not satisfy both of the equations
