Answer:
the equation of the line will be:
Step-by-step explanation:
Equation of line: x + y = 6
We need to write an equation for the perpendicular line that goes through
(5, 1).
The equation will be in slope-intercept form where m is slope and b is y-intercept
Finding Slope:
Equation of line given is: x+y=6
Writing it in slope-intercept form:
The slope of this line is m = -1 (By comparing it with we get m = -1)
Since the required line is perpendicular, their slopes will be opposite inverse of each other i.e.
So, slope of required line will be: m=1
Now, using the point (5,1) and slope m=1 we can find y-intercept
So, we get y-intercept b = -4
Now, the equation of required line, having slope m=1 and y-intercept b = -4
So, the equation of the line will be:
Answer:
The third reading must be between 6.3 and 8.1 inclusive.
Step-by-step explanation:
To find the average of three numbers, add the three numbers and divide by 3.
Let the third reading = p.
The average of the three readings is
This average must be between 7.2 and 7.8 inclusive. "Inclusive" means that the values 7.2 and 7.8 are allowed. That means the average must be greater than or equal to 7.2 and less than or equal to 7.8. We can write this as the following inequality.
Simplify the numerator.
Multiply the three sides by 3.
Subtract 15.3 from the three sides.
Answer: The third reading must be between 6.3 and 8.1 inclusive.
