Z varies jointly with x, and y, and z=7 when x= 2, y= 2

fomenos

Answer:

Step-by-step explanation:

Complete question:

Z varies jointly with x and y , x=2 and y=2, z=7. Find z when x=4 and y=8 using joint variation . (I need the problem worked out step by step)

If z varies jointly with x, and y, this is expressed as;

z = kxy

If z=7 when x= 2, y= 2

7 = k(2)(2)

7 = 4k

k = 7/4

To get z when x= 4 and y = 8

z = kxy

z =7/4 (4)(8)

z = 7*8

z = 56

Hence the value of z is 56

Which point is an x interception of the quadratic function f(x)=(x-8)(x+9)

viva [34]

$f(x)=(x-x_1)(x-x_2)\\\\(x_1,\ 0),\ (x_2,\ 0)-x\ interceptions$

$\text{We have}\ f(x)=(x-8)(x+9)=(x-8)(x-(-9))\\\\\text{therefore your answer is:}\\\\(8,\ 0),\ (-9,\ 0)$
