Answer:

6x^3-8x+9.

Step-by-step explanation:

Rearrange the number with its like terms.

i.e. 6x^3+2x-6x-4x+7-1+3.

which will give us 6x^3-8x+9.

Answer:

6x³ - 8x + 9

Step-by-step explanation:

Step 1: Write out expression

2x + 7 + 6x³ - 1 + 3 - 6x - 4x

Step 2: Combine like terms (x)

6x³ - 8x + 7 - 1 + 3

Step 3: Combine like terms (constants)

6x³ - 8x + 9

write an equation in slope intercept form for the line that passes through ( 4, -4) and is parallel to 3 + 4x = 2y - 9​
Kruka [31]

Answer:

y = 2x - 12

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Rearrange 3 + 4x = 2y - 9 into this form

add 9 to both sides

12 + 4x = 2y ( divide all terms by 2 )

6 + 2x = y ← in slope- intercept form

with slope m = 2

• Parallel lines have equal slopes, hence

y = 2x + c ← is the partial equation of the parallel line

To find c substitute (4, - 4) into the partial equation

- 4 =8 + c ⇒ c = - 4 - 8 = - 12

y = 2x - 12 ← equation of parallel line

If f(x) = 2x -1 and g(x) = x^2 what is the value of f(g(-3))? PLZ HELP WILL MARK BRAINLIEST
Arada [10]

Answer:

f(g(-3))= 17.

Step-by-step explanation:

Start evaluating from the inside and work your way out. This means you start with (-3)²=9. Then go and plug that answer in to the equation f(x). f(9)=2(9)-1=17.

Please solve the following question
Hoochie [10]

Question 1:

A = w * l

A = 5432m^2

l = 97

A / l = w

5432 / 97 = 56

w = 56

Question 2:

Perimeter of rectangle = 2w + 2l

P = 336

w = 79

P - 2w = 2l

336 - 158 = 178

178 / 2 = 89

l = 89

Cards are drawn, one at a time, from a standard deck; each card is replaced before the next one is drawn. Let X be the number of
steposvetlana [31]

Cards are drawn, one at a time, from a standard deck; each card is replaced before the next one is drawn. Let X be the number of draws necessary to get an ace. Find E(X) is given in the following way

Step-by-step explanation:

  • From a standard deck of cards, one card is drawn. What is the probability that the card is black and a jack? P(Black and Jack)  P(Black) = 26/52 or ½ , P(Jack) is 4/52 or 1/13 so P(Black and Jack) = ½ * 1/13 = 1/26
  • A standard deck of cards is shuffled and one card is drawn. Find the probability that the card is a queen or an ace.

P(Q or A) = P(Q) = 4/52 or 1/13 + P(A) = 4/52 or 1/13 = 1/13 + 1/13 = 2/13

  • WITHOUT REPLACEMENT: If you draw two cards from the deck without replacement, what is the  probability that they will both be aces?

P(AA) = (4/52)(3/51) = 1/221.

  • WITHOUT REPLACEMENT: What is the probability that the second card will be an ace if the first card is a  king?

P(A|K) = 4/51 since there are four aces in the deck but only 51 cards left after the king has been  removed.

  • WITH REPLACEMENT: Find the probability of drawing three queens in a row, with replacement. We pick  a card, write down what it is, then put it back in the deck and draw again. To find the P(QQQ), we find the

probability of drawing the first queen which is 4/52.

  • The probability of drawing the second queen is also  4/52 and the third is 4/52.
  • We multiply these three individual probabilities together to get P(QQQ) =
  • P(Q)P(Q)P(Q) = (4/52)(4/52)(4/52) = .00004 which is very small but not impossible.
  • Probability of getting a royal flush = P(10 and Jack and Queen and King and Ace of the same suit)
