Answer:
f(2) =30
Step-by-step explanation:
f(1)=15
f(n)=f(n-1)*n
Put in n=2
f(2)=f(2-1)*2
= f(1) *2
= 15*2
=30
Answer:
1 × (3x + 2y = 12)
2 × (4x - y = 5)
3x + 2y = 12
+ (8x - 2y = 10)
= 11x = 22
divide both sides by the coefficient of 'x' (11)
Therefore x = 2
put (x = 2) in equation 1
3(2) + 2y = 12
6 + 2y = 12
2y = 12 - 6
2y = 6
divide both sides by the coefficient of 'y'(2)
Therefore y = 3
Answer:
the second option

Answer: 214.8
Step-by-step explanation:
First move the decimal to the right, in this case 8.95 = 895., then multiply the 24 by 895. to get 21480., you then move the decimal to the left and you get 214.80 or 214.8.
