Answer:

Step-by-step explanation:

11/4 plus 11/4 is 22/4

to make this a whole number and a fraction we subtract 4 from the 22 as many times as we can. we can do this 5 times, with 2 left over.

the answer is 5 2/4, which you can simplify to 5 and a half

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

Liula [17]

<h2>Hello!</h2>

The answer is:

$h(x)=9x-13$

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!

If 4x^2 - 100 = 0, the roots of the equation are

ololo11 [35]

$4x^2-100=0 \ \ \ \ \ \ |+100 \\
4x^2=100 \ \ \ \ \ \ \ \ \ \ \ |\div 4 \\
x^2=25 \\
x=\pm \sqrt{25} \\
x=\pm 5 \\
x=-5 \hbox{ or } x=5$

The answer is (3) -5 and 5.
