Answer:

x = 3 x = -2

Step-by-step explanation:

2[tex]x^{2}[/tex] - 2x - 12 = 0  Divide all the way through by 2

[tex]x^{2}[/tex] -x - 6 = 0   Add 6 to both sides

[tex]x^{2}[/tex] - x = 6  Take the b value of -1 and multiply that by 1/2 and then square your answer

(-1)(1/2) = -1/2 this squared is 1/4  Add 1/4 to both sides

[tex]x^{2}[/tex] - x + 1/4 = 6 + 1/4

[tex](x -1/2)^{2}[/tex] = [tex]\frac{24}{4}[/tex] + [tex]\frac{1}{4}[/tex]

[tex](x -1/2)^{2}[/tex] = [tex]\frac{25}{4}[/tex]

[tex]\sqrt{(x -1/2)^{2} }[/tex] = ± [tex]\sqrt{\frac{25}{4} }[/tex]

x - 1/2 = ± 5/2

x = 1/2 ± 5/2

x = 1/2 + 5/2

x = 6/2 = 3

x = 1/2 - 5/2 = -4/2 = -2

you need to factor this problem, to do this you find the common values that add up to -2 and multiply to -24, which are -6 and 4 then you set it up from that

Answers

Answer:

-4r(-11r + 2r - 14)

Multiply -4 with all the terms inside the parenthesis

-4r*-11r = 44r^2

-4r*2r = -8r^2

-4r*-14 = 56r

Combine

44r^2 - 8r^2 + 56r

Solve the polynomial by completing the square. Show all steps of your work.[tex]x^2 - 2x - 63 =0[/tex]

Answers

Step-by-step explanation:

x^2-2x-63=0

x^2-x(9-7)-63=0

x^2-9x+7x-63=0

x(x-9)+7(x-9)=0

(x+7)(x-9)=0

x=-7

x=9

Answer: x = -9 and x= 7

Step-by-step explanation: By using completing the square method

= x² - 2x-63

= x² -7x+9x -63

= x(x-7)+ 9(x-7)

= (x+9) (x-7)

= x = -9 and x= 7

Solve the polynomial by completing the square. Show all steps of your work.[tex]x^2+10x+14=-7[/tex]

Answers

Answer:

-3, - 7

Step-by-step explanation:

x² + 10x + 14 = -7

x² + 10 x + 21 = 0

Now let's complete the square.

(x + 5)² - 25 + 21 = 0

(x+5)² - 4 = 0

(x+5)² = 4

x + 5 = ± root 4 = ± 2

x = +2-5 or -2-5 = -3 or -7

The values of x that meet the equation x2 + 10x + 14 = -7 are x = -3 and x = -7.

The given equation is: x2 + 10x + 14 = -7.

Transfer the constant term to the opposite side of the equation:

x2 + 10x + 14 + 7 = 0.

Combine comparable terms to simplify the equation: x2 + 10x + 21 = 0.

Complete the square by rewriting the equation with a constant term. To do so, square half of the coefficient of x (which is 10):

Half of ten equals five, and five squared equals twenty-five. Insert 25 into the equation:

x^2 + 10x + 25 + 21 - 25 = 0

Rearrange the terms as follows:

(x2 + 10x + 25) + (21 - 25) = 0.

Reduce the first set of brackets to a perfect square trinomial:

[tex](x + 5)^2 + (-4) = 0[/tex]

Reduce the number of constant terms:

[tex](x + 5)^2 - 4 = 0[/tex]

To find x, take the square root of both sides:

[tex]√((x + 5)^2 - 4) = √0[/tex]

Determine x: x + 5 = 4

To simplify even further, we have: x + 5 = 2

Solve for x separately:

x = -5 + 2 = -3 x = -5 - 2 = -7

As a result, the answers to the equation x2 + 10x + 14 = -7 are x = -3 and x = -7.

Sandra is creating gift baskets with scented soaps and bottles of bubble bath. She has 12 scented soaps and 6 bottles of bubble bath. If she wants all the gift baskets identical without any items left over, what is the greatest number of gift baskets Sandra can make?

Answers

To make identical gift baskets without any items left over, we need to find the greatest common factor (GCF) of the numbers of soaps and bubble baths.

The prime factors of 12 are 2 x 2 x 3, and the prime factors of 6 are 2 x 3.

To find the GCF, we need to identify the common factors and multiply them together. The common factors are 2 and 3, so the GCF is 2 x 3 = 6.

Therefore, Sandra can make 6 identical gift baskets with 2 scented soaps and 1 bottle of bubble bath in each basket.

Answer:6 gift baskets

Step-by-step explanation:

1 of bottles of bubble bath and 2 of scented soaps in each basket.

x=1,3,4,24
y=24,8,6,1
D:
x=0.1,0.3,25,100
y=200,40,0.8,0.2

Answers

Answer:

A, C

Step-by-step explanation:

If it is inversely proportional then y = k/x

Let's try one by one for the options. (im replacing y and x in the equation and finding k to see if k is the same all throughout)

A.

6 = k/1 (k=6)

3 = k/2 (k=6)

2 = k/3 (k=6)

1.5 = k/4 (k=6)

Yes! It's the same everywhere so this is correct!

B.

7.5 = k/2 (k=15)

5 = k/3 (k=15)

3 = k/5 (k=15)

2 = k/7 (k=14)

For the last one k is not the same so nope. It is wrong.

C.

24 = k/1 (k=24)

8 = k/3 (k=24)

k = 6×4 = 24

k = 24×1 = 24

This is correct too.

D.

k = 0.1×200 = 20

k = 0.3×40 = 12

k = 0.8 × 25 = 20

We can already see that k is not the same everywhere.

Only A and C, x and y are inversely proportional for all of the values
