Answer:
2.5 hours
Step-by-step explanation:
The total amount of time studying by students who spent 1/2 an hour studying is the product of the number of students who spent 1/2 an hour studying by 1/2 an hour.
Hence, counting the number of dots on the point marked 1/2 gives the count of students who spent 1/2 an hour studying and multiply this number by 1/2.
Total amount of hours spent = 1/2 * 5 = 2.5 hours
Answer:
x > 3
Step-by-step explanation:
You have the following inequality:
In order to obtain the solution for x, you first apply distribution property in the left term of the inequality:
Next, you sum 2x on both sides, and you subtract 28 on both sides too:
(where you have simplifies similar terms)
Finally, you divide the inequality for -6, but you take into account that the inequality symbol change (because the operation with a negative term):
hence, the solution to the inequality is x > 3
Answer:
see the explanation
Step-by-step explanation:
we know that
If two lines are perpendicular, then their slopes are opposite reciprocal (the product of their slopes is equal to -1)
In the coordinate plane, the x axis (y=0) and y axis (x=0) are perpendicular
however
this definition does not apply to the lines y=0 and x=0.
because
The slope of the horizontal line y=0 is equal to zero and the slope of the vertical line x=0 is undefined
