Hi!
As you got 108800 you should get it but by x and y.
So can you explain it better so that I can help you!

I don't think you wrote the problem out correctly... But this is what I got for X and Y.

Y=2/x-3 make x the subject

Multiply both sides by x - 3 to get :

y(x - 3) = 2

yx - 3y = 2

yx = 2 + 3y

x = (2 + 3y)/y

Hope this helps! Any questions let me know :)

Finding the slope using two points:

The formula for slope is

$\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

In this case...

(-4, 3) and (5, 3)

$y_{2} =3\\y_{1} =3\\x_{2} =5\\x_{1} =-4$

^^^Plug these numbers into the formula for slope...

$\frac{3-3}{5 - (-4)}$

$\frac{0}{9}$

B. 0

^^^This is your slope

Hope this helped!

Tony’s Electronics is marking down the price of a TV 23% from the original price of $175. Which expression can be used to find t

Arlecino [84]

Answer:

The sale price is $\$134.75$

The expression is $\$175(0.77)$

Step-by-step explanation:

we know that

The sale price is equal to subtract the discount price from the original price

The discount price is equal to multiply the original price by the percent discount in decimal form

Let

x ----> the sale price

y ---> discount price

$23\%=23/100=0.23$ ----> percent discount in decimal form

$y=\$175(0.23)=\$40.25$

$x=\$175-y$

substitute

$x=\$175-\$40.25=\$134.75$

therefore

the expression is

$175-0.23(175)\\175(1-0.23)\\175(0.77)$
