While many desert plants have fibrous roots near the surface, creosote bushes have deep taproots to collect water far below the surface. Creosote bushes also grow in a
grid-like pattern, with nearly equal spacing between each plant. Older creosote bushes
release toxins from their roots that kill any young and establishing plants-even creosote
seedlings.
Which statement describes the most likely reason that creosote bushes release toxins
that harm other plants?
Toxins increase the need for pollinators and decrease the bushes' ability to reproduce.
O Toxins decrease competition from neighboring plants and increase the bushes' ability to
reproduce.
Toxins increase the bushes' ability to grow taller and increase their ability to reproduce.
O No answer text provided.
O Toxins decrease the bushes' ability to photosynthesize and decrease their ability to reproduce.

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.

these muscles maintain the blood pressure in the vessels. the smooth muscles are innervated by nerves of the autonomic nervous system. when the muscles contract, they cause vasoconstriction of the vessels and increase blood pressure. when the muscles relax, they enable vasodilation of the   blood vessels hence reduce blood pressure.
