Assume that y varies inversely with x. Ify = 7 when x = 2/3, find
y when x = 7/3.

Y=?

y = 2

Step-by-step explanation:

y varies inversely with x setup is:

y = k/x

7 =  (find 'k')

k = 7/1 · 2/3

k = 14/3

use what you know about 'k' and 'x' to solve for 'y'

y = 14/3 ÷ 7/3  (remember to multiply by the reciprocal when dividing fractions)

y = 14/3 · 3/7

y = 2

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)

true
