I got letter A when I tried it
Answer:
12
Step-by-step explanation:
(8+11+14+13+14+9+15)/7 = 12
Answer:
(i) = 3
(ii) = 20
Step-by-step explanation:
x = 1
y = -2
z = -1
(i) 4x - 3y + 7z
4(1) - 3(-2) + 7(-1)
4 + 6 - 7 = 3
(ii) 2x³ - 6y²z + 3xyz²
2(1)³ - 6(-2)²(-1) + 3(1)(-2)(-1)²
2 + 24 - 6 = 20
6 is neither equal to 0 nor equal to 7, so the last "piece" of h(x) applies. Then
h(6) = 3•6 - 2 = 18 - 2 = 16
1,4,7,10,13,16,19,22,25,28,31,34,37,40,43,46,49,52,55,58,61,64,67,70,73,76,79,82,85,88,91,94,97,100
f(n) = 1 + 3(n-1) = 1 + 3n - 3 = 3n -2
f(22) = 3(22)-2 = 66-2 = 64
