Write your answer as a coordinate point (x,y).

Answers

Answer 1
r Answer:
( 4, -2)

Step-by-step explanation:
{y=x-6
{3x+2y=8

You already have y as your first equation's subject. So, use the content from the y equation and substitute it into the second equation. Then you get,

3x+2(x-6)=8

Solve it like a normal equation for the unknown.

3x+2x-12=8
5x-12=8
5x=20
x=4

Now, substitue the new x we got into the first equation.

y=x-6
y=4-6
y=-2

three bags of chips costs m cents. At this rate, what is the cost, in cents, of one bag of chips?

Answers

Answer: m/3 cents

Step-by-step explanation:

Hi, to answer this question we have to divide the total cost of the chips (m) by the number of bags of chips (3).

Mathematically speaking:

Cost of one bag chip: m/3 cents

Since the total cost is represented by a variable, the individual cost is an expression.

If we replace the value of m by a number we will obtain the result as a number.

Answer:

Step-by-step explanation:

First, subtract 180 and "12x-3", which equals 180-12x+3

Then add 46, "5x+7", and "180-12x+3"

46+5x+7+180-12x+3 = 180

Since the degrees in a triangle add up to 180 degrees, cancel out the 180 degrees from this side "180-12x+3" and the other side "180"

46+5x+7-12x+3=0

46+10-7x=0

Enter the value of b when the expression 8/9x+b is equivalent to 1/9 (8x+5)

Answers

Answer:

b = 5 / 9

Step-by-step explanation:

8/9x + b = 1/9(8x + 5)

Make b the subject of formula.

b = 1/9 (8x + 5) - 8/9x

Multiply through by 9

9b = 9 * 1/9 ( 8x + 5) - 9 * 8/9x

9b = 8x + 5 - 8x

9b = 5

b = 5 / 9

The value of b = 5 / 9

3. Which of the following is equivalent to 3(y – 1 + 2y)? A. 3y – 9 B. 6y – 3 C. 9y – 3 D. 3y – 3

Answers

Final answer:

To solve the equation 3(y - 1 + 2y), distribute the 3 to each term inside the parentheses, combine like terms, resulting in 9y - 3.

Explanation:

To solve the equation 3(y - 1 + 2y), we need to distribute the 3 to each term inside the parentheses:

3 × y = 3y

3 × -1 = -3

3 × 2y = 6y

So the equation becomes 3y - 3 + 6y. Combining like terms, we get 9y - 3. Therefore, the correct equivalent expression is 9y - 3 (Option C).

Final answer:

The correct answer to the given expression 3(y – 1 + 2y) is 9y - 3, after distributing the 3 and combining like terms.

Explanation:

The given mathematical expression is 3(y – 1 + 2y). To simplify it, we should first distribute the 3 across the parentheses and then combine like terms. Here's how:

Step 1: Distribute the 3: 3 × y + 3 × (-1) + 3 × 2y = 3y - 3 + 6yStep 2: Combine like terms (3y and 6y): 3y + 6y = 9y, and you still have the -3 from the previous step.Step 3: The final simplified expression is 9y - 3.

Thus, the correct answer is C. 9y – 3.

3.  83%, or A

Step-by-step explanation:

First you have to create the variables.

If you need to find the probablility of two items, then you first add them.

11+14 = 25.

Now, you add all the numbers.

22+14+5 = 30.

Using that, make a fraction then simplify.

25/30 = 5/6

4: D

Using the same process, add everything but the green balls.

11+5 = 17.

Now add them all up.

What is the remainder in the synthetic division problem below? 1/1 2 -3 3

Answers

Answer:

Step-by-step explanation:

I'm assuming you want to do the following synthetic division:

1 /       1        2        -3        3

                   1          3        0

        --------------------------------

          1        3         0         3            The remainder is 3.

The remainder is -2

The remainder in synthetic division is the constant term of the quotient. To find the remainder of the synthetic division problem above, we can use the following steps:

Arrange the coefficients of the dividend and divisor in descending order of degree.

Set up the synthetic division table as follows:

     2 -3 3 |1

   ---------------

   1

Bring down the first coefficient of the dividend.

Multiply the coefficient we just brought down by the divisor and place the product in the next column.

Subtract the product from the corresponding coefficient of the dividend and place the difference in the next column.

Repeat steps 4 and 5 until we reach the last column.

The remainder is the last number in the bottom row of the synthetic division table.

Following these steps, we get the following synthetic division table:

     2 -3 3 |1

   ---------------

   1  2 -1

   -2 -4 2

   --------

   -2

Therefore, the remainder is -2
