The mass of an object changes with location or altitude above the earth's surface.

true
false

False

Step-by-step explanation:

Mass is defined as the amount of matter within an object which will never change. This question is trying to trick you since most people use the words mass and weight interchangeably which is not true. Weight is the amount of gravitational force acting upon you which does change with altitude but mass does not.

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3
