Answer:

(-2,1)

Step-by-step explanation:

2x+2y=-2

-2y      -2y

2x=-2y-2

^divided 2 on both sides

x=-y-1

8x-3y=-19

8(-y-1)-3y=-19

-11-8=-19

8         8

-11y=-11

^divide both sides by -11

y=1

x=-y-1

^change -y with -1 so x= -1-1

x=-2

x=-2 and y=1

Simplify the following polynomial expression.
victus00 [196]

Answer:

  5x^4 -37x^3 -6x^2 +41x -6

Step-by-step explanation:

We simplify this expression by removing parentheses and combining like terms. Parentheses are removed using the distributive property.

<h3>Form the product</h3>

The product of the final pair of polynomials in parentheses is ...

  (-4x^3 +5x -1)(2x -7) = (-4x^3 +5x -1)(2x) +(-4x^3 +5x -1)(-7)

  = -8x^4 +10x^2 -2x +28x^3 -35x +7

  = -8x^4 +28x^3 +10x^2 -37x +7

<h3>Combine with remaining sums</h3>

  = (5x^4 -9x^3 +7x -1) + (-8x^4 +4x^2 -3x +2) - (-8x^4 +28x^3 +10x^2 -37x +7)

  = (5 -8 -(-8))x^4 +(-9 -28)x^3 +(4 -10)x^2 +(7 -3 -(-37))x +(-1 +2 -7)

  = 5x^4 -37x^3 -6x^2 +41x -6

In a​ lottery, 6 numbers are randomly sampled without replacement from the integers 1 to 38. Their order of selection is not imp
inna [77]

Answer: Our required probability is 0.328.

Step-by-step explanation:

Since we have given that

there is number on the lottery is from 1 to 38.

6 numbers are selected.

We need to find the probability of holding a ticket that has zero winning numbers out of the 6 numbers selected for the winning ticket.

So, it should be other than 6 numbers.

Remaining numbers = 38-6 = 32

So, our probability becomes

\dfrac{^{32}C_6}{^{38}C_6}\\\\=\dfrac{906192}{2760681}\\\\=0.328

Hence, our required probability is 0.328.
