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        <em>add 8 to both sides</em>

2x-8+8\neq0+8

2x\neq8             <em>divide both sides by 2</em>

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

Quadrilateral FLAG has coordinates F(1,5), L(6,3), A(3,-1), and G(-2,1). Which
Anettt [7]

Answer:

  • B. Quadrilateral FLAG is a parallelogram because opposite sides are parallel.

Step-by-step explanation:

<em>Refer to attached.</em>

Plot the point and connect in order FLAG.

<u>We see </u>

  • FL ║ GA
  • GF ║ AL
  • FA and GL are not perpendicular

<u>All the above can be confirmed by calculating the slopes:</u>

  • m(FL) = (3 - 5)/(6 - 1) = -2/5
  • m(GA) = (1 + 1)/(-2-3) = -2/5
  • These are same.
  • m(GF) = (5 - 1)/(1 + 2) = 4/3
  • m(AL) = (3 + 1)/(6 - 3) = 4/3
  • These are same
  • m(FA) = (-1 - 5)/(3 - 1) = -3
  • m(GL) = (3 - 1)/(6 +2) = -1/4
  • These are negative but not reciprocal

The quadrilateral is a parallelogram.

Correct choice is B

The inequality below represents h, the number of hours Ellie need to work this week to earn at least $360 by the end of the mont
Gnom [1K]

Answer:

The answer to your question is 10 hours.

Step-by-step explanation:

Inequality                            12h + 240 > 360

Solve the inequality as if it was an equation

                                           12h > 360 - 240

                                           12h > 120

                                           h > 120 / 12

                                           h = 10 hours

Let's evaluate some number of hours

If h = 3                        12(3) + 240 > 360

                                  36 + 240 > 360

                                          276 > 360     Incorrect, she needs to work more

                                                                 than 3 hours

If h = 5                         12(5) + 240 > 360

                                   60 + 240 > 360

                                           300 > 360     Incorrect, she needs to work more

                                                                 than 5 hours

If h = 7                          12(7) + 240 > 360  

                                    84 + 240 > 360

                                          324 > 360      Incorrect she needs to work more

                                                                 than 7 hours

If h = 11                          12(11) + 240 > 360  

                                     132 + 240 > 360

                                              372 > 360   Correct, she needs to work at least

                                                                   10 hours.

∠ A and ∠B are vertical angles. Find each angle if, m∠ A=7x+2 and m∠ B=4x+11. Solve for x
tino4ka555 [31]

Answer:

x=3

Step-by-step explanation:

Vertical angles are equal so

<A = <B

7x+2 = 4x+11

Subtract 4x from each side

7x+2-4x = 4x+11-4x

3x+2 =11

Subtract 2 from each side

3x+2-2 = 11-2

3x = 9

Divide by 3

3x/3 = 9/3

x=3
