Select all expressions that are equivalent to x2 - 4x – 32.
0 (x – 16)(x + 2)
(x + 2)(x – 16)
(2 – )(x + 4)
(x + 8)(x – 4)
(x + 4)(x – 8)
(x – 4)(x+8)

First off, we factor out the expression:

[tex] \displaystyle \large{y = 2 {x}^{2} - 12x + 16} \\ \displaystyle \large{y = 2 ( {x}^{2} - 6x + 8) }[/tex]

In the bracket, separate 8 out of the expression.

[tex] \displaystyle \large{y = 2[ ( {x}^{2} - 6x + 8)] }\\ \displaystyle \large{y = 2[ ( {x}^{2} - 6x) + 8]}[/tex]

In x^2-6x, find the third term that can make up or convert it to a perfect square form. The third term is 9 because:

[tex] \displaystyle \large{ {(x - 3)}^{2} = {x}^{2} - 6x + 9}[/tex]

So we add +9 in x^2-6x.

[tex] \displaystyle \large{y = 2[ ( {x}^{2} - 6x + 9) + 8]}[/tex]

Convert the expression in the small bracket to perfect square.

[tex] \displaystyle \large{y = 2[ {(x - 3)}^{2} + 8]}[/tex]

Since we add +9 in the small bracket, we have to subtract 8 with 9 as well.

[tex] \displaystyle \large{y = 2[ {(x - 3)}^{2} + 8 - 9]} \\ \displaystyle \large{y = 2[ {(x - 3)}^{2} - 1]}[/tex]

Then we distribute 2 in.

[tex]\displaystyle \large{y = 2[ {(x - 3)}^{2} - 1]} \\ [/tex]

[tex]\displaystyle \large{y = 2[ {(x - 3)}^{2} - 1]} \\ \displaystyle \large{y = [2 \times {(x - 3)}^{2} ]+[ 2 \times ( - 1)] } \\ \displaystyle \large{y = 2 {(x - 3)}^{2} - 2 }[/tex]

Remember that negative multiply positive = negative.

Hence the vertex form is y = 2(x-3)^2-2 or first choice.

[tex]\\ \rm\hookrightarrow (x,y)=(3,-6)[/tex]

Answer:

(3, - 6 )

Step-by-step explanation:

Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is

( [tex]\frac{x_{1}+x_{2} }{2}[/tex] , [tex]\frac{y_{1}+y_{2} }{2}[/tex] )

Here (x₁, y₁ ) = (10, - 3) and (x₂, y₂ ) = (- 4, - 9) , then

midpoint = ( [tex]\frac{10-4}{2}[/tex] , [tex]\frac{-3-9}{2}[/tex] ) = ( [tex]\frac{6}{2}[/tex] , [tex]\frac{-12}{2}[/tex] ) = (3, - 6 )

Answer:

11th term is -45x+56

Answer:

a_11 = -45x + 56

Step-by-step explanation:

An arithmetic sequence has a constant difference which can be found by subtracting a term from the next term.

constant difference = d = -9x + 11 - (-5x + 6)

d = -9x + 11 + 5x - 6

d = -4x + 5

The nth term of an arithmetic sequence is

a_n = a_1 + (n - 1)d

a_11 = a_1 + (11 - 1)(-4x + 5)

a_11 = -5x + 6 + 10(-4x + 5)

a_11 = -5x + 6 - 40x + 50

a_11 = -45x + 56

Answer:

7 x 9 = 63 7 is a FACTOR of 63

9 is a FACTOR of 63

7 and 9 are even DIVISORS of 63

63 is a MULTIPLE of 7 and 9

63 is a PRODUCT of 7 and 9

63 is evenly DIVISIBLE by 7 or 9

Writing 63 as a product of as many factors will be: 7 × 9, 3 × 21, 9 × 7 and 21 × 3.

The factors of 63 include 1, 3, 7,9, 21 and 63.

Since we've been given the information that we should not use 1 as a factor when multiplying according to the question, then the 63 as a product of its factors will be:

3 × 21 = 63

7 × 9 = 63

9 × 7 = 63

21 × 3 = 63
