1. In some places, hot water from underground can shoot up into the air through a hole in the ground. When this happens, the ground surrounding the water increases in temperature. What happens to the molecules in the ground
when the temperature of the ground increases?
a
More heat molecules combine with the molecules in the ground.
b
The energy of the molecules in the ground decreases.
с
The energy of the molecules in the ground increases.
d
The cold energy of the molecules in the ground decreases.

i believe the answer is c

i'm guessing this is from edg enuity so the answers would be, from top to bottom,

d. groundwater flows through the subsoil and deposits minerals.

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.
