Answer: Y =24

Step-by-step explanation:first get the constant. X=KY substituting x and y in the equation is 3=K8 Therefore K = 3/8 =0.375

If x is 9 find y when the constant k is 0.375 from the equation x=ky

Is Y = X÷K is 9÷0.375 =24.

If f(x) = -3x - 5 and g(x) = 4x - 2, find (F- g)(x).
yan [13]

<u>Answer:</u>

If f(x) = -3x - 5 and g(x) = 4x - 2 then (f - g)(x) = -7x - 3

<u>Solution:</u>

We need to determine the value of (f - g)(x)

Given that the function is f(x) = -3x - 5 and the other function is g(x) = 4x - 2

The value of (f - g)(x) can be found by as follows:

<em>(f - g)(x) = f(x) - g(x)</em>

On substituting the given value of f(x) and g(x) we get

(f - g)(x) = (-3x - 5) - (4x - 2)

Upon solving we get

(f - g)(x) = -3x -5 -4x + 2 = -7x -3

Hence the value of (f - g)(x) is equal to -7x - 3
