If y varies jointly as x and the cube of z and y=16 when x=4 and z=2 then y=0.5 when x=-8 and z=-3?

Evgesh-ka [11]

Answer: F (False)

Step-by-step explanation:

Jointly variation has the following form:

y=kxz

Where k is a constant of propotionality.

Substitute values:

If y=16, x=4 and z=2, then k is:

$16=k(4)(2)^{3}\\k=1/2$

If x=-8 and z=-3 the the value of y is:

$y=(1/2)(-8)(-3)^{3}\\y=-108$

Then the answer is FALSE.

JK= 4x+3,<br> JL= 47, <br> KL= 9x+5<br> Find KL

Anuta_ua [19.1K]

Answer:

<h2>x = 3</h2><h2></h2>

Step-by-step explanation:

JK + KL = JL

(4x + 3) + (9x + 5) = 47

4x + 9x = 47 - 3 - 5

13x = 39

x = 39 / 13

x = 3
