Step-by-step explanation:

f(x)=4x+5

g(x)=6x+4,

first: (f*g)=(4x+5) (6x+4)=24x²+46x+20

next:(f*g)(0)=((g*f)=24x²+46x+20=20

Hi,

f°g means : apply first g then f . so calculate "g" and then use result as "x" in f.

g°f means : you apply first f then g

so : f°g = 4 (g (x)) +5

4 (6x+4) +5 = 24x+16+5 = 24x+21

If x^2 - 6xy = z - 9y^2, make x the subject of the formula

alukav5142 [94]

$~~~~x^2-6xy=z-9y^2\\\\\implies x^2- 2\cdot x\cdot 3y + (3y)^2 - (3y)^2 = z-9y^2\\ \\\implies (x-3y)^2 -9y^2 = z-9y^2\\\\\implies (x-3y)^2 = z\\\\\implies x - 3y =\pm\sqrt z\\\\\implies x = 3y\pm\sqrt z$
