Suppose that y varies inversely with x.write an equation for the inverse variation. Y=6 when x=8
sasho [114]

Answer: y = 48/x

Step-by-step explanation:

y ∝ 1/x

Introducing the proportionality constant, we have

y = k/x

substituting the value of x and y , we have

6 = k/8

k = 48

Therefore the equation becomes

y = 48/x

Solve for x. Show each step of the solution.<br> 2.5(4-x)+12=21-4(2.5x+7)
erastova [34]

Answer:

x=-58/15

Step-by-step explanation:

distribute first 10-2.5x+12=21-10x-28

Simplify(add the numbers) 22-2.5x=-7-10x

move the variable to the left side 22-2.5x+10x=-7

move the constant to the right side -2.5x+10x=-7-22

simplify like terms 7.5x=-29

divide by 7.5                       x=-58/15

alternate forms are x=-3 13/15                or  x=-3.86
