8x-4y-2
1.75 because you would divide 3.5 by 2
Step-by-step explanation:
x = 2 is, as you can see, parallel to the y-axis.
perpendicular to this (= crosses the original line in an angle of 90 degrees) is then a line parallel to the x-axis.
that means y is constant. all points on that line will have the same y value.
and we know one point already : (3, -2)
so all points of the perpendicular line will have y = -2
and that is the equation of the perpendicular line :
y = -2
Answer:
7
232
Step-by-step explanation:
First
Normally the average of something is total something over total time. I'll do it that way and see what happens.
The total time is ( 4 - 2) = 2 hours.
f(x) = 2^4 - 2 = 14
Change = 14/2 = 7 per hour.
Second
Average = Increase / time.
10000 (1.02)^10 - 10000 * (1.02)^5
10000*1.22 - 10000*1.104
12,200 - 11040
1160
The average per year = 1160 / 5 = 232
