What is the correct answer for both?

Answers

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

Bacteria doubles every 10 minutes. If you start with 2 bacteria in a petri dish, how many bacteria will there be after 40 minutes?

Answers

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!

Casey is making a flower arrangement with roses r and carnations c the cost of each rose is $0.50 and the cost of each carnation is $0.10 . the arrangement has a total $20. how many of each flower did Casey put in his arrangement

Answers

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.
