If y varies directly as x and y = 144 when x = 12, what is the value of y when x = 17?
olasank [31]
Direct variation:
y=kx

y=144 when x=12.
144=12k \\ k=\frac{144}{12} \\ k=12

y=? when x=17.
y=12 \times 17 \\&#10;y=204

y=204 when x=17.

Type the correct answer in the box. Use numerals instead of words. If necessary, use / for the fraction bar.

Answer:

-5/2 x -33/4

Step-by-step explanation:

(-11/2 x + 3) -2 (-11/4 x -5/2)

(-11/2 x + 3/1) -2 (-11/4 x -5/2)

The LCM of 2 and 1 is 2, and the LCM of 4 and 2 is 4.

(-11/2 x + 6/2) -2 (-11/4 x -20/4)

( -5/2x) -2 (-31/4)

-5/2x -2 -31/4

-5/2x -2/1 -31/4

LCM of -2 -31/4 is 4

-2/4 -31/4

-33/4

-5/2x -33/4 in simplest form.
