This would be 1 * i * -1 * -i * 1 = -i * -i * 1 = i^2 = -1
Answer:
y=1/2x-3
Step-by-step explanation:
First, let's put the line into slope intercept form
2y+4x=12
subtract 4x from both sides
2y=-4x+12
divide by 2
y=-2x+6
the slopes of perpendicular lines are negative and reciprocal. If you multiply the slopes of the lines together, the result is -1. Therefore, to find the slope of the perpendicular line, use this formula:
-2m=-1
divide by -2
m=1/2
so the slope of the perpendicular line is 1/2
here is the new line so far:
y=1/2x+b (b is a place holder)
now, since the line passes through the point (8,1), it means that (8,1) is a solution of the line. So we can substitute it into the equation
1=1/2(8)+b
1=4+b
subtract 4 from both sides
-3=b
so the line is y=1/2x-3
Hope this helps!
you can either subtract 6-(-3) or do a number line -3, -2, -1, 0, 1, 2, 3, 4, 5, 6
count up from -3, and you'll get 9, same as subtracting 6 from -3. answer is 9 degrees F
(6.259 x 10^10)/3.43 x 10^3)
Divide the 6.259 by 3.43 and get 1.82
Divide 10^10 by 10^7 and get 10^3
So the answer is
1.82 x 10^3
