Here the only limitation on the domain exists when the denominator is equal to zero, as division by zero has no meaning and is not "allowed" because of its meaninglessness. :)

Factor the denominator to find the excluded values of x...

3x^2+5x-12

3x^2+9x-4x-12

3x(x+3)-4(x+3)

(3x-4)(x+3)

So x CANNOT equal 4/3 or -3 (all other real values of x are part of the domain) so the domain is:

x=(-oo, -3),(-3, 4/3),(4/3, +oo)

Use the distance formula to find the distance between the points (−10,−9) and (−3,8).
gizmo_the_mogwai [7]

Step-by-step explanation:

the distance can be seen as Hypotenuse of a right-angled triangle with its legs being the x and y coordinate differences.

so, we use Pythagoras

c² = a² + b²

with c being the Hypotenuse (the side opposite of the 90 degree angle).

distance² = (-10 - -3)² + (-9 - 8)² = (-7)² + (-17)² = 49+289 =

= 338

distance = sqrt(338) = sqrt(2×169) = 13×sqrt(2) =

= 18.38477631...

Find the value of k. the diagram is not to scale
Nesterboy [21]
Given:
<span>∠SRT ≅ ∠STR, 
m∠SRT = 20, 
m∠STU = 4x

Since </span>∠SRT ≅ ∠STR,  then m∠STR = 20.

m∠STR + m∠STU = 180°
20 + 4x = 180
4x = 180 - 20
4x = 160
4x/4 = 160/4
x = 40

The value of x is 40.



I hope this is what you're looking for.
