Answer:
( 2, -1)
Step-by-step explanation:
(X1 + X2)/2 , (Y1 + Y2)/2
(6-2)/2 , (3-5)/2
4/2 , -2/2
2 , -1
First off, you have to find a common denominator between 6 and 9 which is 18, so to rewrite your equation using the common denominators it would be 15/18+(-8/18)-(-36/18) when you combine these it equals (7/18)-(-36/18)=43/18
Answer:
z=12
Step-by-step explanation:
It is given that x varies jointly as y and z, it means



where, k is the constant of proportionality.
It is given that x=8 when y=4 and z=9


Divide both sides by 36.


The value of k is 2/9.

We need to find the value of z when x=16 and y=6.
Substitute x=16 and y=6 in the above equation.


Multiply both sides by 3.

Divide both sides by 4.

Therefore, the value of z is 12.
It is a whole number and integer.
