The value of y varies jointly with the values of x and z When x = 4 and z = 10, the value of y is 360.
Igoryamba

Answer:

A

Step-by-step explanation:

Joint variation is given by:

y=kxz

Where k is some constant.

We are given that y = 360 when x = 4 and z = 10. Therefore:

360=k(4)(10)

Solving for k:

40k=360\Rightarrow k=9

Therefore, our equation is:

y=9xz

Then when x = 5 and z = 12:

y=9(5)(12)=540

The answer is A.

Part 1. Using the two functions listed below, insert numbers in place of the letters a, b, c, and d so that f(x) and g(x) are in
dem82 [27]

There is no b unfortunately

Find inverse of x+a

  • x+a=y

interchAnge

  • y+a=x
  • y=x-a

Inverse is

  • f^{-1}x=x-a

Now

  • x-a=cx-d
  • x-cx=a-d
  • x(1-c)=a-d
  • x=a-d/1-c

So

You can have any number according to this but

  • c must not be 1
  • a and d must not be equal .
  • All three should belongs to integers set

Note:-

As there is no b given in question (May be missed in typing) Part-2 's equation can't be executed and part 3 also
