Answer: Choice A
The notation P(15,10) refers to the equation
P(n,r) = (n!)/(n-r)!
where n = 15 and r = 10. So,
P(15,10) = (15!)/(15-10)!
P(15,10) = (15!)/(5!)
which is close to the original expression but it is missing the 10! part in the denominator. Instead you'll use a combination formula

Step-by-step explanation:
Answer:
y = 2x + 10
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 2. thus
y = 2x + c ← is the partial equation
To find c substitute (- 3, 4) into the partial equation
4 = - 6 + c ⇒ c = 4 + 6 = 10
y = 2x + 10 ← equation of line
