Answer:
D. 120
Step-by-step explanation:
Array formula: A (n, p) = n! / (n -p)!
At where:
n = Total number of elements in the set.
p = Quantity of elements per arrangement
A (5.5) = 5! / (5-5)! = (5x4x3x2x1) / 0!
By definition: 0! = 1
Then: 120/1 = 120
Answer:
Scalene Acute

Answer:
y = -4/5x + 2/5
Step-by-step explanation:
Slope form of an equation is y = mx + b
Sub in x and y coordinates and slope then isolate for b
-2 = -4/5(3) + b
-2 = -12/5 + b
-2 + 12/5 = b
b = -10/5 + 12/5
b = 2/5
Sub in b and the slope into the slope form equation
y = (-4/5)x + 2/5
