This primary immunodeficiency is extremely rare in the population, with less than 200 cases reported. patients with this disease have impaired lymphocytes, macrophages and neutrophils that do not allow these cells to travel to the site of an infection, and consequently many patients succumb to infections before the age of 2. what disease am i?

The answer is Leukocyte adhesion deficiency type 1. This is a sickness that reasons the immune system to breakdown, subsequent in a type of immunodeficiency. Immuno-deficiencies are circumstances in which the immune system is not capable to defend the body efficiently from foreign attackers such as viruses, bacteria, and fungi. 

answer: i don't know

explanation:

you need to provide a picture, otherwise i can't tell you.

if you can provide one, i'd be more than happy to you with this!

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.
