1 answer:

5 0

X = y - 3

x + 3y = 13

x + 3y = 13 (replace x with y-3)

y - 3 + 3y = 13

4y - 3 = 13

4y = 13 + 3

4y = 16

y = 16/4

y = 4

x = y - 3

x = 4 - 3

x = 1

The answer is A. (1,4)

Z varies directly as x^3 and inversely as y^3. if z=59 when x=8 and y=8, find Z if x=3 and y=4

marissa [1.9K]

$z=\dfrac{kx^3}{y^3}\\\\\\59=\dfrac{k\cdot 8^3}{8^3}\\k=59\\\\\\z=\dfrac{59x^3}{y^3}\\\\\\z=\dfrac{59\cdot 3^3}{4^3}=\dfrac{1593}{64}$
