Someone help me pls.....

Answer:

$\dfrac{-x+5}{6x^2-x-12}$

Step-by-step explanation:

The denominators are the same. You can add the numerators without any extra work.

$=\dfrac{(4x+5)-(5x)}{6x^2-x-12}=\dfrac{-x+5}{6x^2-x-12}$

The denominator factors as (2x-3)(3x+4), so there are no factors that will cancel with the numerator.

Three cards are randomly selected from a standard 52-card deck, one at a time, with each card re- placed in the deck before the

hammer [34]

Answer:

$\frac{1}{4}$

Step-by-step explanation:

Three cards are randomly selected from a standard 52-card deck.

Number of heart cards in a deck = 13

Each card replaced in the deck before the next one is picked.

Probability of first card is heart = $P_{1}=\frac{13}{52}$

After replacement, the probability of second card is heart = $P_{2}=\frac{13}{52}$

after replacement, the probability of third card is heart = $P_{3}=\frac{13}{52}$

P = $\frac{13}{52}$ × $\frac{13}{52}$ × $\frac{13}{52}$

= $\frac{39}{156}$

= $\frac{1}{4}$

The probability of all three cards are hearts is $\frac{1}{4}$

Angelina_Jolie [31]

ANSWER

C(2,-6)

EXPLANATION

The solution set to given inequality is the shaded region.

The points are also located in the graph above.

The only point that falls in the solution region is C(2,-6)

The ordered pair that is in the solution set is C(2,-6)

The third option is correct.
