Achange of such as a liquid changing to a gas, is an example of a physical change. a. energy b. state c. location d. charge

The answer is state because solid, liquid and gas are matter of states

the answer is a change of state

Explanation:

you are not changing the energy, and you’re definitely not changing the location. The location wouldn’t even matter in a situation like this It’s not charge because you’re not adding anything or giving it a conductor. So your answer is B. State

answer-

the statement that f(x) = |x+a| + b has exactly one x-intercept is sometimes correct.

solution-

it solely depends on b, whether the function will have one or two or zero x intercept.

this plot of the given function, f(x) = |x+a| + b will be the basic absolute value graph i.e v shape, with vertex translated to (-a, b), instead of origin.

1-   if b is zero, the graph will have exactly one x-intercept, at x= -a

2- if b is positive, the whole graph will be above the x-axis, hence it will have no x-intercepts.

3- if b is negative, the graph will be below the x-axis, hence it will have two x-intercepts.

∴ the statement is sometimes true.
