Aperson who is at least 18 years old is considered an adult. write an inequality that represents this situation

Step-by-step explanation:

The question concerns the use of inequalities in correct mathematical language.

When we have the condition "at least", it means something is greater than and equal; when we have the condition "at most", it is lesser than and equal.

In this case, we must use the former condition. Let's denote age with the letter a.

Then, the correct inequality is going to be:

b.-4 units

all you   do is count how many times you move

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
