Answer:

Choice B is correct.

Step-by-step explanation:

Firstly, we have to find constant of variation.

y= kx         eq(1)

Given y= -96 and x= 24

put above values in eq(1)

-96=k(24)

dividing above equation by 24

-96/24=24k/24

-4=k

so eq(1) becomes y=-4x

Secondly, we have to find value of x when y=-164

-164=-4x

dividing by -4 by above equation.

-164/(-4)=-4x/(-4)

41=x

so, k=-4 and x=41.

Answer:

B

Step-by-step explanation:

30. You want to solve for k and use it with a different y-value.


... y = kx


... -96 = k·24


... -96/24 = k = -4


For y = -164, you have


... -164 = -4·x


... -164/-4 = x = 41


The coefficient of variation is -4, x is 41.

ikadub [295]

Answer:

$1015.11

Step-by-step explanation:

Compounded interest rate formula: A = P(1 + r/n)^t

Step 1: Plug in known variables

A = 1000(1 + 0.005/12)^36

Step 2: Multiply it all together

1000(1.00042)^36

1000(1.01511)

1015.11

This is a pretty bad bank considering only giving you .5% interest per month.
