A. (-2)to the power of 2 - (-8) + 1
B. (-2)to the power of 2 - (8) + 1
C. -2 to the power of 2 - (-8) + 1
D. -2 to the power of 2 - 8 + 1

Answer:

1. 6a-2b+4

2. 3a-3b+9

3. x=1

4. x=9

Answer:

x = -3

Step-by-step explanation:

m(x) = -2x + 7

13  = -2x + 7

6 = -2x

x = -3

Answer: I think the answer is 32 bacteria after 40 minutes.

Step-by-step explanation:

I think that's right because the bacteria that have previously multiplied will also be multiplying. 2 becomes 4, 4 becomes 8, etc. until you've reached 40 minutes. (I'm honestly unsure, but I think this is right?) I hope this helped!

Step-by-step explanation:

Answer:

-19

Step-by-step explanation:

x= -5       y = -2

-x^2 - 4xy + y^2

- -5^2 -4(-5 x -2) -2^2                      Plug in

+ 5^2 -4(-5 x -2) -2^2                      Change the signs for - -5

  5^2 - 2^2 - 4(10)                           Place Liked Terms together

  25 - 4 - 40                                    Subtract

      21 - 40

         -19

Answer:

([tex]\frac{2}{3}[/tex], 2 )

Step-by-step explanation:

Given the 2 equations

3x + [tex]\frac{1}{2}[/tex] y = 3 → (1)

6x - y = 2 → (2)

Multiplying (1) by - 2 and adding to (2) eliminates the term in x, that is

- 6x - y = - 6 → (2)

Add (2) and (3) term by term to eliminate x

- 2y = - 4 ( divide both sides by - 2 )

y = 2

Substitute y = 2 into either of the 2 equations and solve for x

Substituting into (2)

6x - 2 = 2 ( add 2 to both sides )

6x = 4 ( divide both sides by 6 )

x = [tex]\frac{4}{6}[/tex] = [tex]\frac{2}{3}[/tex]

Solution is ( [tex]\frac{2}{3}[/tex], 2 )

Answer:

the answer to x is 111

Step-by-step explanation:

A+B=X

Since its extended you add the two legs together

Hope this helps!

Answer:

111 degrees

Step-by-step explanation:

Angles in a triangle add up to 180 degrees, so we do 180-36-75 to find out the missing angle (=69). Then, angles on a straight line add up to 180 degrees too, so we do 180-69=111 degrees. :)

Answer:

7.5 inches per hour

Step-by-step explanation:

Given that:

Morning low tide at beach = 12 inches

Afternoon tide after 6 hours = 57 inches

Average number of inches tide changed per hour :

(Afternoon tide - morning tide) / number of hours

(57 inches - 12 inches) / 6 hours

45 inches / 6 hours

= 7.5 inches per hour

there is your answer. hope this helps

Answer:

Step-by-step explanation:

A percent greater than 100% represents a comparison between one value that is greater than another value, with the second value being the base, represented by 100%. In situations like rainfall and revenue, these kinds of comparisons are common.

Each employee makes 35 x 7.60 = 266 per week.

105 employees x 266 = 27,930 per week total pay.

27930 x 10 % = 27930 x 0.10 = 2,793 more per week.

PART A: 2,875

Step-by-step explanation:

Answer: x=8

Step-by-step explanation:

Answer:

r+c=80

.50r+.10c=20

Step-by-step explanation:

each rose costs $0.50

each carnation costs $0.10

The number of roses is r, and the number of carnations is c.

the arrangement has a total of 80 flowers, so we have that:

r + c = 80

the cost is $20, so we have:

r*0.5 + c*0.1 = 20

so our system of equations is:

r + c = 80

r*0.5 + c*0.1 = 20

and we can also solve it; for this isolate one of the variables in the first equation:

r = 80 - c

now let'r replace this in the second equation:

(80 - c)*0.5 +c*0.1 = 20

40  - c*0.4 = 20

c = 20/0.4 = 50

this means that we have 50 carnations, and the other 30 are roses.

Answer:

14)   C (-2, 4)

15)   D (-3, -3)

Step-by-step explanation:

-6x + 4y = 28

6x + 9y = 24

-6x + 4y = 28

4y = 28 + 6x

y = 7 + 1.5x

6x + 9y = 24

6x + 9(7 + 1.5x) = 24

6x + 63 + 13.5x = 24

19.5x + 63 = 24

19.5x = -39

x = -2

-6x + 4y = 28

-6(-2) + 4y = 28

12 + 4y = 28

4y = 16

y = 4

____________

4x - 4y = 0

-4x + 3y = 3

4x - 4y = 0

4x = 4y

x = y

-4x + 3y = 3

-4(y) + 3y = 3

-4y + 3y = 3

-1y = 3

y = -3

4x - 4y = 0

4x - 4(-3) = 0

4x + 12 = 0

4x = -12

x = -3
