2. What is the relationship between atmospheric pressure and the density of gas particles in an area of decreasing pressure? (2 points) O As alr pressure in an area decreases, the density of the gas particles in that area decreases.
O As air pressure in an area decreases, the density of the gas particles in that area increases.
O As air pressure in an area decreases, the density of the gas particles in that area remains constant.
As air pressure in an area decreases, the density of the gas particles in that area increases and decreases in an alternating pattern.

what are the options? add them, then i will be glad to .

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.
