You have 
of one type of coin and 
of another type of coin.
To find the total number of coins, you need to add the two values together.
Answer:
y = 2x-2
Step-by-step explanation:
First find the slope of the line
x+2y=6
2y = -x+6
y = -1/2x +3
This is in slope intercept form ( y = mx+b) so -1/2 is the slope
We want a line that is perpendicular so take the negative reciprocal of the slope
- ( 1/ (-1/2)) = 2
The slope of the perpendicular line is 2
y = 2x+b
Substitute the point into the equation
8 = 2(5) +b
8 = 10+b
-2 =b
The equation of the line perpendicular is
y = 2x-2
You just plug in the values.
[3*(-2)]^3 - (-2 - 4*5)^2
(-6)^3 - ( - 2 - 20)^2
-216 - (-22)^2
-216 - (484)
-216 - 484
-700
