Determine the equation of the inverse of y=-4/x+1 The inverse is y=-a/x-b where a = a0 and b = a1

leva [86]

<span>y=-4/x+1 is ambiguous, since it's not immediately clear whether you meant

-4
y = -4/x + 1 or y = ---------
x+1

I'm going to assume that the latter is what you meant.

1. Interchange x and y, obtaining:

-4
x = --------
y+1

2. Solve this for y, obtaining y+1 = -4/x, or xy + x = -4, or

-x - 4
xy = -x-4, or y = ---------
x

-1 -1 4
3. Replace y with f (x): f (x) = -1 - -----
x

This last result has the correct form.</span>

The proportionality constant (y to x) is

NeTakaya

Answer:

the constant of proportionality k is given by k=y/x where y and x are two quantities that are directly proportional to each other. Once you know the constant of proportionality you can find an equation representing the directly proportional relationship between x and y, namely y=kx, with your specific k.

Vlad spent 20 minutes on his history homework and then completely solved x math problems that each took 2 minutes to complete wh

frozen [14]

Answer:

y = 2x + 20

$y\geq 20$

$x\geq 0$

Step-by-step explanation:

Vlad spent 20 minutes on history. Then Vlad spent 2 minutes on each math problem for homework, this is 2x. So in total, he spent 20+2x on homework. Depending on how many problems he did, the total time y can be found. This is the equation 20+2x=y.

If Vlad did 0 math problems then he spent at least 20 minutes on homework from history. This is the constraint $y\geq 20$ .

We also know Vlad can do many math problems but the least amount he did was 0, so the second constraint is $x\geq 0$ .
