Step-by-step explanation:
4x + 2xy=
4×4 + 2×4×-3
= 16 + (-24)
= - 8
Step-by-step explanation:
Tn=ar^(n-1)
r=-10/-5=2
a=-5
Tn=-5×(2)^(n-1)
Tn=-5•(2)^(n-1)
an=5•(2)^(n-1)
Direct variation equal is written as : y = kx
K is the constant of variation.
12 = k4
12/4 = k
k = 3
y = 3x
Answer: <span>B. y = 3x </span>
