2logb - 3logb = log8b - log4b

Elden [556K]

Answer:

b=1/2

Step-by-step explanation:

2logb - 3logb = log8b - log4b

log $b^{2}$ - log $b^{3}$ = log8b - log4b

log( $\frac{1}{b}$ ) = log(2)

∴1/b = 2

∴b = 1/2

Which equation represents a proportional relationship? A) y = x 8 B) y = 8 x C) y = x 8 + 8 D) y = 8 x + 8

Liula [17]

Answer:

B y=8x

Step-by-step explanation:

A proportional relationship must go through the point x=0, y=0 and be in the form y=kx where x is a constant

A) y = x^8

B) y = 8 x

C) y = x^8 + 8

D) y = 8 x + 8

The only points that is in the form y= kx is option B

C and D do not go through x=0, y=0 and A is not in the form y=kx where k is a constant
