1: Triple the quantity of a number “n” plus 4 equals 27. what would the expression look like?

[ Triple the quantity of a number “n” ] 3n

[ plus 4 ] + 4

[ equals 27 ] = 27

[ all together ] <u>3n + 4 = 27</u>

<u />

<u>Solving:</u>

[ given ] 3n + 4 = 27

[ subtract 4 from both sides ] 3n = 23

[ divide both sides by 3 ] n = 7 \frac{2}{3}

 

2:Seventeen equals seven less than three times a number “n” what would the expression look like?

[ Seventeen equals ] 17 =

[ seven less than ] - 7

[ three times a number “n” ] 3n

[ all together ] <u>17 = 3n - 7</u>

<u />

<u>Solving:</u>

[ given ] 17 = 3n - 7

[ add 7 to both sides ] 24 = 3n

[ divide both sides by 3 ] 8 = n

Have a nice day!

PLEASE HELP ASAP!!! CORRECT ANSWERS ONLY PLEASE!!!<br><br> Graph g(x) = 3x^2 - 12x - 3
Paul [167]

Answer: Vertex = (2, -15)  2nd point = (0, -3)

<u>Step-by-step explanation:</u>

g(x) = 3x² - 12x - 3

      = 3(x² - 4x - 1)

          a=1   b=-4  c=-1

Find the x-value of the vertex by using the formula for the axis of symmetry: x = \dfrac{-b}{2a}

x = \dfrac{-(-4)}{2(1)}

      = \dfrac{4}{2}

         = 2

Find the y-value of the vertex by plugging the x-value (above) into the given equation: g(x) = 3x² - 12x - 3

g(2) = 3(2)² - 12(2) - 3

       = 12  - 24 - 3

       = -15

So, the vertex is (2, -15)  ←  PLOT THIS COORDINATE

Now, choose a different x-value.  Plug it into the equation and solve for y. <em>I chose x = 0</em>

g(0) = 3(0)² - 12(0) - 3

       = 0  - 0 - 3

       = -3

So, an additional point is (0, -3)  ←  PLOT THIS COORDINATE

Consider an experiment with a deck of 52 playing cards, in which there are 13 cards in each suit, two suits are black, and two s
lakkis [162]

Answer:

<u>P (E1) = 1/2 or 50%</u>

<u>P (E2) = 3/13 or 23%</u>

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Number of playing cards = 52

Number of suits = 4

Number of cards per suit = 13

Number of black suits = 2

Number of red suits = 2

2.  Suppose E1 = the outcome is a red card and E2 = the outcome is a face card (K, Q, J). Determine P(E1 or E2).

P (E1) = Number of red cards/Total of playing cards

P (E1) = 26/52 = 1/2 = 50%

P (E2) = Number of face cards/Total of playing cards

P (E2) = 12/52 = 3/13 = 23%
