Answer:
fg(4) = 6
Step-by-step explanation:
f(x) = -x + 7
g(x) = x - 3
fg(x) = -(x-3) + 7
= -x + 3 + 7
fg(4) = -4 + 10
= 6
Answer:
3 and 21/22
Step-by-step explanation:

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.
