Answer:

y = 8 or y = -14

Step-by-step explanation:

Solve for y over the real numbers:

abs(y + 3) - 4 = 7

Add 4 to both sides:

abs(y + 3) = 11

Split the equation into two possible cases:

y + 3 = 11 or y + 3 = -11

Subtract 3 from both sides:

y = 8 or y + 3 = -11

Subtract 3 from both sides:

Answer:  y = 8 or y = -14

You are dealt two cards successfuly without replacement from a shuffled deck of 52 playing card. Find the probability that first
katen-ka-za [31]

The simplified expression is (\frac{4}{663})

Step-by-step explanation:

Here, the total number of cards in a given deck = 52

let E : Event of drawing a first card which is King

Total number of kings in the given deck = 4

So, P(E) = \frac{\textrm{The total number of king}}{\textrm{The total number of cards}} = \frac{4}{52}  = (\frac{1}{13} )

Now, as the picked card is NOT REPLACED,

So, now the total number of cards = 52 - 1 = 51

Total number of queen in the deck is same as before = 13

let K : Event of drawing a second card which is queen

So, P(K) = \frac{\textrm{The total number of queen}}{\textrm{The total number of cards}} = (\frac{4}{51}  )

Now, the combined probability of picking first card as king and second as queen  = P(E) x P(K)  = (\frac{1}{13}) \times(\frac{4}{51}) = (\frac{4}{663} )

Hence, the simplified expression is (\frac{4}{663})

Suppose that y varies inversely with x. Use the information to find k, and then choose the equation of variation. x = 2 when y =
Sergeeva-Olga [200]

Answer:

y = \frac{22}{x}

Step-by-step explanation:

given that y varies inversely with x then the equation relating them is

y = \frac{k}{x} ← k is the constant of variation

To find k use the condition x = 2 when y = 11

k = yx = 11 × 2 = 22

y = \frac{22}{x} ← equation of variation
