F(x) = 2x – 1 g(x) = 7x – 12 What is h(x) = f(x) + g(x)?
Liula [17]
<h2>Hello!</h2>

The answer is:

A.

h(x)=9x-13

<h2>Why?</h2>

To solve the problem, we need to perform the shown operation.

We have the functions:

f(x)=2x-1\\g(x)=7x-12

So, performing the following operation, we have:

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

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

h(x)=9x-13

Hence, we have that the correct option is:

A. h(x)=9x-13

Have a nice day!

2/3 of the sum of three times a number and six is 10. what is the number?
mestny [16]

9514 1404 393

Answer:

  3

Step-by-step explanation:

Let x represent the number. The problem statement tells you ...

2/3(3x +6) = 10

  2x +4 = 10 . . . . . . use the distributive property

  x +2 = 5 . . . . . . . . divide by 2

  x = 3 . . . . . . . . . . .subtract 3

The number is 3.

__

<em>Comment on the solution</em>

The above shows an "alternative" solution method. The more usual way this might be done is ...

  2(3x +6) = 30 . . . . . multiply by 3 to clear fractions

  6x +12 = 30 . . . . . . . eliminate parentheses

  6x = 18 . . . . . . . . . . . subtract 12

  x = 3 . . . . . . . . . . . . divide by 6
