Answer:

y=14

Step-by-step explanation:

y \propto 1/x

y=k/x

4=k/7

4 \times 7 = k

28=k

y=28/x

y=28/(2)

y=14

Answer:

y = 14

Step-by-step explanation:

y ∝ \frac{1}{x}

=> y = \frac{k}{x}     -------------(1)

<em><u>Where k is the constant of proportionality</u></em>

Now,

x = 7, y = 4

<em>Putting in (1)</em>

4 = \frac{k}{7}

So,

=> k = 28

Now y = ? when x = 2

<em>Putting x and k in (i)</em>

y = \frac{28}{2}

y = 14

tangare [24]

sorry if I'm wrong. I got confused because you put 56+3 twice.×= 63
56+3=59=x-4 (this is with subtraction sign)

I didnt know if that a subtracting or negative so here both

56+3=x-4 (this is with the negative sign)
x= -14.75
