Answer:
The required equation of the line is:

Step-by-step explanation:
Given the equation

comparing the equation with the slope-intercept form

Here,
so the slope of the line is -4.
As we know that the slope of the perpendicular line is basically the negative reciprocal of the slope of the line, so
The slope of the perpendicular line will be: 1/4
Therefore, the point-slope form of the equation of the perpendicular line that also intersects the point (8, 1) is:


add 1 to both sides


Answer:
range of the test scores is 48
Step-by-step explanation:
60,72,94,108
108- 60=48
Answer:
n = 2
Step-by-step explanation:
Given
(n - 4) - 3 = 3 - (2n + 3)
Multiply through by 2 to clear the fraction
n - 4 - 6 = 6 - 2(2n + 3) ← distribute
n - 10 = 6 - 4n - 6 ( add 4n to both sides )
5n - 10 = 0 ( add 10 to both sides )
5n = 10 ( divide both sides by 5 )
n = 2
3/5 x 7/7= 21/35
4/7x 5/5= 20/35
They both have a common denominator
