2.83 is your answer. It actually isn't hard. Look up some YouTube videos or go to Khan Academy. It helps a lot if you actually care enough to pay attention. Anyway, I used a calculator.

Answer:

<h2> $( f - g)(x) = \frac{2x - \sqrt{x} + 14 }{3x}$ </h2>

Step-by-step explanation:

$f(x) = \frac{2x + 6}{3x} \\ \\ g(x) = \frac{ \sqrt{x} - 8}{3x}$

To find ( f - g)(x) , subtract g(x) from f(x)

That's

$( f - g)(x) = \frac{2x + 6}{3x} - \frac{ \sqrt{x} - 8}{3x}$

Since they have a common denominator that's 3x we can subtract them directly

That's

$\frac{2x + 6}{3x} - \frac{ \sqrt{x} - 8}{3x} = \frac{2x + 6 - ( \sqrt{x} - 8) }{3x} \\ = \frac{2x + 6 - \sqrt{x} + 8 }{3x} \\ = \frac{2x - \sqrt{x} + 6 + 8 }{3x}$

We have the final answer as

<h3> $( f - g)(x) = \frac{2x - \sqrt{x} + 14 }{3x}$ </h3>

Hope this helps you

What is the equation of the line h Th ya has a y intercept of (0,-3) and passes through the point (-9,-9)

Nikolay [14]

Answer:

The line equation is given as: 3 y = 2 x - 9

Step-by-step explanation:

Here, Y intercept is at point ( 0.-3)

So, at x = 0, y = -3

or, C = -3

Also, the point on the equation line is (x,y) = (-9,-9)

Now, by <u>SLOPE INTERCEPT FORM</u> of a line equation,we get:

y = m x + C : m = slope of line ......... (1)

So, substituting the values of C and (x,y) , we get:

-9 = m (-9) + (-3)

or, -9 + 3 = - 9 m

or, m = -6/-9 = 2/3

or, m = 2/3

Now, substitute the value of m back in to the line equation (1)

$y = m x + C \implies y = (\frac{2}{3}) x - 3\\\implies 3y = 2x - 9$

Hence, the line equation is given as: 3 y = 2 x - 9.

Pls help the question is here (12points) DUE TO DAY

scZoUnD [109]

Answer:

$\bf Area= 90\;in$

Step-by-step explanation:

<u>Area of ABCD = L * W</u>

$\bf 6\times 12$

$\bf 72 \;in^2$

<u>Area of EFGC:- L * W</u>

$\bf 6 \times 3$

$\bf 18\; in^2$

<u>Now, the area of the combind rectangles:-</u>

ABCD + EFGC

$\bf 72+18$

$\boxed{\bf 90\; in}$
