Find an
expression which represents the sum of (-X – 7) and (-9x + 6) in
simplest terms.

Answer:

(x+2)^2-6

Step-by-step explanation:

(x+2)^2 = x^2 + 4x + 4

x^2 + 4x + 4 -6 = x²+4x-2

Answer:

(x + 2)² - 6

Step-by-step explanation:

Using the method of completing the square

add/subtract ( half the coefficient of the x- term)² to x² + 4x

x² + 2(2)x + 4 - 4 - 2

= (x + 2)² - 6

Answer:

4

Step-by-step explanation:

k=4÷12=1÷3

t=12×1÷3=4

Answer:

profit of $140,910

there is a missing number I will assume that the probability is 1 in 11,000

company expected revenue per policy = $600

companies expected expense = 400,000 * (1/11,000) = -36.36

profit per policy = $536.64

$536.64*250 = $140,910

Step-by-step explanation:

Two or more points are said to be coplanar if they all lie on the same plane.

Based on the given diagram, we can see that the points N, R, S, and W all lies on the same plane A. Due to this fact, we can conclude that N, R, S, and W are coplanar.

Assuming any of the four points fall outside plane A, then we can say they are not coplanar.

Based on the explanation above, we can conclude that points N, R, S, and W all lie on the same plane.

Answer:

2x + 2

Step-by-step explanation:

Given

[tex]\frac{x^3+2x^2}{x}[/tex] ( divide each term on the numerator by x )

= x² + 2x

Differentiate each term using the power rule

[tex]\frac{d}{dx}[/tex] (a[tex]x^{n}[/tex] ) = na[tex]x^{n-1}[/tex] , then

[tex]\frac{d}{dx}[/tex] (x² + 2x ) = 2x + 2

Step-by-step explanation:

Use formula of midpoint

( x1+x2)/2 , (y1+y2)/2

2+8 = 10/2 = 5 (x)

3+ -4 = -1/2 (y)

(5,-1/2) is the final answer

Answer:

Correct choice is option A. 6a + 8b ≤ 200

                                             7a + 5b ≤ 150

---> cereal A with grams will be multiplied by the sodium available in one gram of cereal A

----> The solution from the above equation would then be added to the cereal B with grams as well as its sodium content per grams.

6a + 8b ≤ 200

---> Cereal A's grams × Cereal A's calories + Cereal B's grams × Cereal B's calories is ≤ 150

so, 7a + 5b ≤ 150

Answer: f/2 = -5

Step-by-step explanation:

Given

f/2 + 9 = 4

Subtract 9 on both sides

f/2 + 9 - 9 = 4 - 9

f/2 = -5

Multiply 2 on both sides

f/2 × 2 = -5 × 2

f = -10

Answer:

The sum of 5 numbers with an average of 5 more than 5 is 50

Step-by-step explanation:

Let the first five letters of the alphabet be equal to the 5 numbers being summed.

Let the average be represented by the following equation:

[tex]\frac{a + b + c + d + e}{5} = 10[/tex]

To find the sum, we should get rid of the denominator. To do that we multiply 5 on both sides

[tex]\frac{a + b + c + d + e}{5} (5) = 10(5)\\a + b + c + d + e = 50[/tex]

Therefore, we see to it that the sum of the 5 numbers is 50.
