Answer:
m = 30
Step-by-step explanation:
(m/3) - 6 = 4
Add 6 to both sides
m/3 = 10
multiply both sides by 3
m = 30
Step-by-step explanation:
Total students-30
No.of students pass their English test-24
24/30 X 100=80%
So,80%students pass their test
Answer:
y= -1/2x +1
Step-by-step explanation:
use the slope equation to find the slope, and the the point slope equation to solve for your equation
First, let's re-arrange to slope-intercept form.
x + 8y = 27
Subtract 'x' to both sides:
8y = -x + 27
Divide 8 to both sides:
y = -1/8x + 3.375
So the slope of this line is -1/8, to find the slope that is perpendicular to this, we multiply it by -1 and flip it. -1/8 * -1 = 1/8, flipping it will give us 8/1 or 8.
So the slope of the perpendicular line will be 8.
Now we can plug this into point-slope form along with the point given.
y - y1 = m(x - x1)
y - 5 = 8(x + 5)
y - 5 = 8x + 40
y = 8x + 45
