Given:
The inequality is:
To find:
The solution for the given inequality and graph of it.
Solution:
We have,
Divide both sides by -20 and change the sign of inequality because inequality is divided by a negative number.
Therefore, the solution for the given inequality is .
All the value less than 4 are in the solution set. It means all the values on the left side of 4 are in the solution set.
Since 4 is not included in the solution set, therefore there is an open circle at 4.
The graph for the given inequality is shown below:
D because each day he runs for 40 more minutes. To explain, if you add 40 minutes to 40 minutes, you get 80 minutes, or 1 hour and 20 minutes. Then if you add 40 minutes to 1 hour and 20 minutes you get 1 hour and 60 minutes, or 2 hours. Continuing this process, the next logical answer would be 2 hours and 40 minutes.
Answer:
2√3
Step-by-step explanation:
So √12 is in radical form. I think what you are asking for is to reduce the expression to its **simplest** readical form.
So 12 = 4*3, √12 = √4 * √3.
So 12 = 4*3, √12 = √4 * √3.
We can ‘reduce’ this by noting that √4 =2, so the expression becomes 2√3.
This cannot be further reduced because 3 isn’t a square or divisible by a square, so 2√3 is the simplest radical form.
6x + 7 = 8x - 15
7 = 2x - 15
22 = 2x
11 = x
