If f(x) = 3x + 10x and g(x) = 4x - 2, find (f - g)(x).
Anika [276]

Answer:

(f-g)(x)=9x+2

Step-by-step explanation:

The function  (f-g)(x) means subtract the expression of g function from the expression of f function.

So we have:  (3x+10x) - (4x - 2) = (13x) - (4x -2) = 13x -4x +2 = 9x+2

Hence  (f-g)(x)=9x+2

suppose y varies jointly as x and z. Find y when when x =-4 and z=25, if y=206 when x=-6 and z=-11. Round your answer to the nea
EastWind [94]
Y = kxz
Find k first to get the equation.
206 = k*(6*11)
206 = 66*k
Divide both sides by 66.
3.12 = k

y = 3.12xz
y = 3.12(-4*25)
y = 3.12(-100)
y = -312
