I assume that the equation you mean is below:
To find roots for this equation, we have to get rid of the denominator. We can do by multiplying both sides by 3.
Factor w-term out (common factor)
Answer
- The roots of quadratic equation are 0,-3
What is the slope of a trend line that passes through the points (5, 80) and (7, 65)?
2 answers:
The slope of a trend line that passes through the points (5, 80) and (7, 65) is -7.5.
Step-by-step explanation:
If the line is passing through two points (x1, y1) and (X2, y2). The slope (m) can be calculated using following formula.
In this case,
x1 = 5
x2 = 7
y1 = 80
y2 = 65
By putting the values in formula, we get
or
m = -7.5
Therefore, the slope of a trend line that passes through the points (5, 80) and (7, 65) is -7.5.
