Yeah this guy above me is right, I took Algebra 1 Honors so I think I'd know. If someone in the future needs the work, all you really need to do to figure this out is input the x coordinate found in the (x,y) so for example (0, 3) into the equation f(x) = 3x + 3 so...

f(x) = 3 (0) + 3 = f(x) = 3 WHATEVER YOU HAVE LEFT IS THE Y COORDINATE SO YOU KNOW WHEN YOU INPUT X INTO THE EQUATION YOU WILL FIND Y WHICH IS 3 (0, 3).

Answer:

The tip would be worth $2.19

Step-by-step explanation:

x - is the full bill

1/20 x = $0.73

Solve for x:

Multiply both sides by 20.

<u>20</u>*(1/20 x) = <u>20</u>*(0.73)

x = 14.6

Now we just have to find 15% of x to find the tip.

3/20 (14.6) = 2.19

So, the tip would be worth $2.19

8u/u^2-18u+81 subtract 72/u^2-18u+81

Karo-lina-s [1.5K]

Your question is:
$\frac{8u}{u^2-18u+81} -\frac{72}{u^2-18u+81}$
Then, the above formula equate:

$\frac{8u-72}{u^2-18u+81}$
Factor out 8 from the numerator we get:
$\frac{u-9}{u^2-18u+81}$
Factorization of the denominator:
$\frac{u-9}{(u-9)^2}$
Simplifying the numerator and the denominator by (u-9) we get:
$\frac{1}{(u-9)}$
