Find the domain of the rational expression: x-3/2x-8

miss Akunina [59]

Answer:

$\huge\boxed{x\neq4\to x\in\mathbb{R}\backslash\{4\}}$

Step-by-step explanation:

$\dfrac{x-3}{2x-8}$

We know: the denominator must be different than 0.

Therefore

$2x-8\neq0$ add 8 to both sides

$2x-8+8\neq0+8$

$2x\neq8$ divide both sides by 2

$\dfrac{2x}{2}=\dfrac{8}{2}\\\\x\neq4$

A rectangular plot of farmland will be bounded on one side by a river and on the other three sides by a single-strand electric

allochka39001 [22]

I'm fairly certain that using that wire you can have the same area no matter what dimensions there are, but if you do the square root, or $\sqrt{}$ of 19,001,900 then you get 4359.11688. So your dimensions are 4359.11688 x 4359.11688. To get area, do length x width to get $1.9*1 0^{7}$ .

Hope this helped! If it did, please give me a good rating and mark me brainiest.

What is the measure of

Helen [10]

Answer:

A = 37 degrees ; B = 82 degrees

Step-by-step explanation:

the angle A plus 143 must measure 180 degrees

angle A = 180 - 143 = 37 degrees

the sum of the inner angles of a triangle is 180 degrees

A + B + C = 180

37 + B + 61 = 180
