Question

g(x)=3x
h(x)=3x+a
find (g -5h) (x)
my answer is -12x+20

Answer 1

so 3x - 5 times h
5(3x+a) = 15x+5a
so we have 3x - (15x + 5a)
which is -12x -5a

Answer 2

h(x)= 3x+4

Answer 3

my mistake on the problem

Answer 4

g(x) = 3x
h(x) = 3x + 4

(g - 5h)(x)
= g(x) - 5h(x)
= 3x - 5(3x + 4)
= 3x - 15x - 5(4) = (3 - 15)x - 20
= -12x - 20

Answer 5

right thanks man. I had put the problem wrong

Answer 6

g(x) = 3x
h(x) = 3x + 4

(g - 5h)(x)
= g(x) - 5h(x)
= 3x - 5(3x + 4)
= 3x - 15x - 5(4)
= (3 - 15)x - 20
= -12x - 20

Answer 7

its good thanks
