A is inversely proportional to b. If a=7.2 when b=-4, what will a equal when b=6?

Step-by-step explanation:

To find the value of a when b=6 we must first find the relationship between them.

The statement

a is inversely proportional to b is written as

where k is the constant of proportionality

When a = 7.2 , b = -4

So we have

k = 7.2 × - 4

k = - 28.8

So the formula for the variation is

When

b = 6

That's

We have the final answer as

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
