Answer:

  y = 15/x

Step-by-step explanation:

An inverse proportion has the equation ...

  y = k(1/x) . . . . k is the constant of proportionality

__

Solving for k, we find ...

  k = xy

The coordinates of the given point can be used to find k:

  k = (3)(5) = 15

Then the equation of the graph is ...

  y = 15/x

Yes his reasoning is correct because you can not cut a person in half. you can not be born with half of a body so you would have to round your result to the nearest whole number which in this case is 2 so he would technically be correct

Express x% of 4 plus y% of 5 as a percentage of 11
djverab [1.8K]
X% of 4 = x*4/100 = 0.04x

y% of 5 = x*5/100 = 0.05y

x% of 4 + y% of 5 = 0.04x + 0.05y

How you express a number, n, as percentage of 11?: [n/11]*100= 9.10n %

Then make n = 0.04x + 0.05y

9.10n %= 9.10[0.04x + 0.05y] %= (0.3656x + 0.455y)%

Confirm that f and g are inverses by showing that f(g(x)) = x and g(f(x)) = x. (5 points)
lara31 [8.8K]
F(x)=(x-8)/(x+7). g(x)=(-7x-8)/(x-1). Plug in g(x) into f(x), f(g(x))=[(-7x-8)/(x-1)-8]/[-7x-8)/(x-1)+7], which can be simplified as (-7x-8-8x+8)/(-7x-8+7x-7)=-15x/-15=x. Plug in f(x) into g(x), g(f(x))=[-7*(x-8)/(x+7)-8]/[(x-8)/(x+7)-1]=(-7x+56-8x-56)/(x-8-x-7)=-15x/-15=x, as desired.
