4, find y when X = 12. 2. If y varies inversely as x and y= 3 when x= 4, find y when
x 6.
3. w varies directly as x and y and inversely as v?and w= 1200 when​

Complete question for 3.

W varies directly us X and Y and in inversely as V² and W= 1200 when X=4, Y=9 and V=6. Find W when X= 3 , Y=12 and V=9.

y = 2

W = 533 1/3

Explanation:

y α 1/x

y = k/x

y = 3 ; x = 4

3 = k/4

k = 3*4 ; k = 12

Hence,

y = 12/x

When ; x = 6

y = 12/6

y = 2

3.)

W α XY α 1/V

W = kXY/V²

W= 1200 when X=4, Y=9 and V=6

1200 = k*4*9 / 6²

1200 = 36k / 36

k = 1200

W = 1200XY/V²

W when X= 3 , Y=12 and V=9

W = (1200*3*12) / 9²

W = 43200 / 81

W = 533 1/3

this question is given using the conditional form. conditional tenses are is used when talking about hypothetical situations and probabilities. also, this is used when making polite requests. so comprarías is the conjugation of the verb comprar that matches the second person singular in the conditional. finally:
