1. Human activities, such as the burning of fossil fuels, transfer carbon from the geosphere to the atmosphere. Which of the following processes also contribute to transferring carbon to the atmosphere ? A. photosynthesis formation of fossil fuels C. precipitation D. volcanic eruptions

as resources become scarce because of population growth, the growth decreases after few years due to lack of resources and food.

the answer to your question is sperm

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.
