Answer:
120
Step-by-step explanation:
Using the definition
n
= n! / (n - r ) !
where n! = n(n - 1)(n - 2) ....... × 3 × 2 × 1
Hence
5
= 5! / 0! = 5! ← 0! = 1
5 = 5! = 5 × 4 × 3 × 2 × 1 = 120
Answer:
(f+g)(x)=x²+2x-6
Step-by-step explanation:
(f+g)(x)=2x+1+x²-7
collect like terms
(f+g)(x)=x²+2x+1-7
according to mathematics x² is not a like term of 2x so don't add the them
(f+g)(x)= x²+2x-6
Answer:
f(-10) = 6
Step-by-step explanation:
f(x) is simply just the name of the function. x will be your dependent variable that you'll use to plug into the equation.
Since they want you to find f(-10), you'll then plug -10 in where x was and solve.
f(-10) = -2((-10)+7)
f(-10) = -2(-3)
f(-10) = 6
