Answer:

3x-y=2

Step-by-step explanation:

y=3x-2

(y-3x)=-2

-3x+y=-2

change the signs on both sides

3x-y=2

=3x-y=2

Y=7

Step-by-step explanation:

Move all terms not containing y to the right side of the equation.

4y=22+6

Then add 22 and 6.

4y=28

Divide each term in 4y=28 by 4

4y÷4=28÷4

Cancel the common factor of 4 in the first part of the equation so it looks like this...

y=28÷4

Divide 28 by 4.

Therefore y=7

Answer:

? =8.77

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

sin theta = opposite side/ hypotenuse

sin 20 = 3 / ?

? = 3/ sin 20

? = 8.7714132

To the nearest hundredth

? =8.77

We need to get x by itself.

We do that by subtracting 5 from both sides.

This leaves us with x = -7.

So x = -7 is the solution.

Answer:

The final answer is [tex]x = -7[/tex] .

Step-by-step explanation:

Solve the equation:

[tex]5 + x = -2[/tex]

Subtract both sides by 5:

[tex]5 - 5 + x = -2 -5[/tex]

[tex]x = -7[/tex]

So, therefore, [tex]x = -7[/tex] is the final answer.

Answer:

x = 9

y = 6

Step-by-step explanation:

3x+6i=27+yi

The real components have to be equal and the imaginary components have to be equal

3x = 27

divide by 3

3x/3 = 27/3

x=9

6i = yi

Divide by i

6 = y

Answer:

x=9, y=6

Step-by-step explanation:

Step-by-step explanation:

we have

3x+6i=27+yi

Equate the Real Numbers

3x=27

solve for x

Divide by 3 both sides

x=27/3=9

Equate the  Imaginary Numbers

6i=yi

Simplify

6=y

Rewrite

y=6

therefore

x=9, y=6

Correct Question

A standard deck of 52 cards contains 4 suits: hearts, clubs, diamonds, and spades. Each suit consists of cards numbered 2 through 10, a jack, a queen, a king, and an ace.

Anthony decides to pick one card at random from a standard deck of 52 cards. Let A be the events that he chooses an ace and H be the event that he chooses a heart.

What is P ( A or H), the probability that the card Anthony chooses is either an ace or a heart?​

Answer:

2/13

Step-by-step explanation:

From the question, we have in total, 52 cards.

Step 1

We find the probability that Anthony chooses an Ace.

Number of ace cards in each of four suits namely spades, hearts, diamonds and clubs = 1

Therefore, total number of ace cards out of 52 cards = 4

P(A) = 4/52

Step 2

We find the probability that Anthony chooses an Ace.

Probability that Anthony chooses an heart P(H) = 4/52

Step 3

The probability that the card Anthony chooses is either an ace or a heart

P ( A or H) = P(A) + P(H)

= 4/52 + 4/52

= 8/ 52 = 2 /13

Answer:

13/b I think

Step-by-step explanation:

Answer:

a = -1/2 & k = 3/7

Step-by-step explanation:

Solve for a over the real numbers:

24 a^3 + 8 a^2 + 6 a + 4 = 0

The left hand side factors into a product with three terms:

2 (2 a + 1) (6 a^2 - a + 2) = 0

Divide both sides by 2:

(2 a + 1) (6 a^2 - a + 2) = 0

Split into two equations:

2 a + 1 = 0 or 6 a^2 - a + 2 = 0

Subtract 1 from both sides:

2 a = -1 or 6 a^2 - a + 2 = 0

Divide both sides by 2:

a = -1/2 or 6 a^2 - a + 2 = 0

Divide both sides by 6:

a = -1/2 or a^2 - a/6 + 1/3 = 0

Subtract 1/3 from both sides:

a = -1/2 or a^2 - a/6 = -1/3

Add 1/144 to both sides:

a = -1/2 or a^2 - a/6 + 1/144 = -47/144

Write the left hand side as a square:

a = -1/2 or (a - 1/12)^2 = -47/144

(a - 1/12)^2 = -47/144 has no solution since for all a on the real line, (a - 1/12)^2 >=0 and -47/144<0:

Answer: a = -1/2

______________________________________

Solve for k over the real numbers:

(7 k - 3) (k^2 - 2 k + 7) = 0

Split into two equations:

7 k - 3 = 0 or k^2 - 2 k + 7 = 0

Add 3 to both sides:

7 k = 3 or k^2 - 2 k + 7 = 0

Divide both sides by 7:

k = 3/7 or k^2 - 2 k + 7 = 0

Subtract 7 from both sides:

k = 3/7 or k^2 - 2 k = -7

Add 1 to both sides:

k = 3/7 or k^2 - 2 k + 1 = -6

Write the left hand side as a square:

k = 3/7 or (k - 1)^2 = -6

(k - 1)^2 = -6 has no solution since for all k on the real line, (k - 1)^2 >=0 and -6<0:

Answer: k = 3/7
