Answer: 2, 6
<u>Step-by-step explanation:</u>
Triangle Inequality Theorem states that the sum of two sides must be GREATER than the third side.
RS + ST > RT and RS + RT > ST and ST + RT > RS
2x + 4x > 12 2x + 12 > 4x 4x + 12 > 2x
6x > 12 12 > 2x 12 > -2x
x > 2 6 > x -6 < x
2 < x x < 6 invalid
Answer: 2 < x < 6
Graph: O----------------------O
2 6
<em> Note: -6 is invalid because you cannot have a negative length. </em>
6 3/4 hours = (6*60)+45 = 405 minutes
7/5 = 1,4
405 minutes * 1,4 = 567 minutes
= Jack spent 9 3/4 hours
we have
the equation of the line is 
the points are

<u>Method 1</u>
we know that
A relationship between two variables, x, and y, represent a direct variation if it can be expressed in the form
or 
In this problem we have a direct variation
The constant of proportionality k is equal to the slope of the line

so

therefore
<u>the answer is</u>
the slope of the line is equal to

<u>Method 2</u>
we know that
the formula to calculate the slope between two points is equal to

we have

substitute in the formula



therefore
<u>the answer is</u>
the slope of the line is equal to

Answer:The relationship between the two variables is known as correlation. If the points are close to each other and making a straight line in the scatter plot, then two variables are said to have a high correlation. If the points are equally distributed in the scatter plot, the correlation is said to be low, or zero.
