Answer:
{
}
The number line is attached.
Step-by-step explanation:
By definition Set-builder notation is a mathematical shorthand used to provide specific details about a set.
In this case, you have the following interval:
![(-6,2]](https://tex.z-dn.net/?f=%28-6%2C2%5D)
You can obsseve that the left hand contains a parentheses, which means that -6 it is not included, then:

The right hand contains a bracket, which means that 2 is included:

The inequality is:

Therefore, in Set-builder notation this is:
{
}
Observe the number line attached. Since -6 is not included, you must use an unfilled circle. Since 2 is included, you must use a filled circle.
Answer:
9x - 45
Step-by-step explanation:
9 * x = 9x and 9 * -5 = -45. Therefore the answer is 9x - 45
Answer:
49.5 mi
Step-by-step explanation:
Area of a triangle is A = (height) X (base) / 2
So if you plug in the numbers you get:
806.9 = (32.6) X (base) / 2
1613.8 = (32.6) X (base)
1613.8 / 32.6 = base
base = 49.5 mi
The answer to your question is 10 seconds. I know this because:
distance divided by speed=time
let t=time
t=2*6(30/36)=10
t=10
So, it took Boris a total of 10 seconds to run up the out of service elevator.
Hope this helps!
