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?

Answer

Find out the find the value of y when x is 2 .

To prove

As given

If y varies directly as x .

y = kx

Where  k is the constant of proportionality.

y is 48 when x is 6,

48 = 6k

k = 8

Now calculate the value of y when x is 2 .

y = 8 × 2

y = 16

Therefore the  value of y is 16  when x is 2 .

hey there!

if she's saving for six months, let's divide the total number we need for the trip by six, dividing it into the amount that needs to be saved for each month.

500 ÷ 6 =

she needs to save at least this amount each month, so we should use this symbol: ≥

let x be the amount she saves each month.

your final answer is x ≥

hope this !
