72.5 as decimal or 72 1/2 as fraction
Answer:
Step-by-step explanation:
To solve this problem, first you have to use the slope formula of 
.
y2= (-7)
y1=6
x2=4
x1(-6)
Solve.
Therefore, the correct answer is -13/10.
I don't know I think c=23 hope you get it right good luck lol

Answer:
A) 3y = x + 16
Step-by-step explanation:
The equation of a perpendicular line can be found by swapping the x- and y-coefficients and negating one of them. The constant will be chosen to match the given point.
Swapping coefficients, we get ...
-3y = x + c
Negating the y-coefficient gives ...
3y = x + c
Filling in the given point, we have ...
3(5) = -1 + c
16 = c
The equation of the perpendicular line can be written as ...
3y = x + 16 . . . . matches choice A
_____
Note that choice A is the only equation that gives a line with positive slope. The given equation has negative slope, so its perpendicular must have positive slope.
For every side you just add 90 to your equation. so #4 would be 360-125-125-55=(55)
