Question

F(x) = 2x – 1 g(x) = 7x – 12 What is h(x) = f(x) + g(x)?

Answer 1

h(x)=9x-13

Explanation:

We want to find out what h(x) is. We know what h(x) is equal to, which is

h(x)= f(x)+g(x)

We know that f(x)=2x-1 and g(x)=7x-12. Substitute the expressions in.

h(x)= (2x-1)+(7x-12)

Simplify by combining like terms. Add all the terms with a variable (x), then all the terms without a variable, or constants.

h(x)=(2x+7x)+(-1+-12)

Add 2x and 7x.

h(x)=(2+7)(x)+(-1+-12)

h(x)= 9x+(-1+-12)

Add -1 and -12.

h(x)= 9x+(-13)

h(x)=9x-13

Answer 2

h(x)=9x-13

Solution,

`h(x) = f(x) + g(x) \\ \: \: \: \: \: \: \: = 2x - 1 + 7x - 12 \\ \: \: \: \: \: \: = 2x + 7x - 1 - 12 \\ \: \: \: \: \: \: = 9x - 13`

hope this helps...

Good luck on your assignment..
