Question

If y varies directly as x, and y is 48 when x is 6, which expression can be used to find the value of y when x is 2?
E
o y- 48 (2)
y (43)
O ya 4036

Answer 1

The expression will be  y =8*2 or y = (48/6)*2

Step-by-step explanation:

The direct proportion is given if y varied directly as x

y∝x

When the proprtionality symbol is removed, a proportionality constant is introduced.

y = kx

as we know y = 48 when x = 6

$48 = k * 6\\k = \frac{48}{6}\\k = 8$

The equation will be:

y = 8x

So when x=2

y = 8*2

y = 16

Hence,

The expression will be  y =8*2 or y = (48/6)*2
