The slope is -3/4
Step-by-step explanation:
You figure this out by using the Rise/Run method.
The rise is how many units up (+) or how many units down (-) the points are away from each other, and rise is how many units to the left or right the points are away from each other.
Since the line is going at a downward angle, we can tell that the slope will be a negative slope. We can see that the 2nd point is 3 units down from the first, and the 2nd point is 4 units to the right of the first one. With this information, we can figure out that the slope is -3/4
Simplify the expression
6² + 9²
6² = 6 x 6 = 36
9² = 9 x 9 = 81
36 + 81 = 117
117 is a rational number ∴ <span>6</span>²<span> plus 9</span>² is rational

Let one piece of the rope be x
Let the other piece of rope be x + 5
These two pieces put together will make 20 feet.
So we say:
x + (x +5) = 20
What is x? We expand the equation.
x + x + 5 = 20
x + x = 20 - 5
2x = 15
x = 7.5
The shorter piece is therefore 7.5 feet.
The longer piece is 7.5 + 5 = 12.5 feet.
<h3>Answer: 71</h3>
==================================
Explanation:
Multiply the values in the second and third columns. Do this row by row.
Row1: 50*55 = 2750
Row2: 75*32 = 2400
Row3: 150*13 = 1950
Add up the products to get 2750+2400+1950 = 7100
Then divide this by the total frequency 55+32+13 = 100 to get 7100/100 = 71
