Answer:

1350

Step-by-step explanation:

If a culture started with 1000 bacteria and after 6 hours it few to 1300 bacteria, there would be 1350 present after 10 hours.

1000 to 1100 is an increase of 100 bacteria per 6 hours.

1100+250= 1350

<em>*please give me brainliest lol*</em>

Step-by-step explanation:

(8r^3 + 2r^2 + 1) - (7 - 7r^3 + 3r^2)

<em>after factoring out the negative, you'll have:</em>

8r^3 + 2r^2 + 1    -7 + 7r^3 - 3r^2

<em>now we combine like terms, and your answer is:</em>

15r^3 - r^2 - 6

How many solutions does the system formed by x - y = 3 and ay + 3a = 0 have for a non zero number a? Explain and show how you ge
dlinn [17]
Solve both equations for y:
x-y=3 \ \ \ |-x \\&#10;-y=-x+3 \ \ \ |\times (-1) \\&#10;y=x-3 \\ \\&#10;ay+3a=0 \ \ \ |-3a \\&#10;ay=-3a \ \ \ |\div a, a \not= 0 \\&#10;y=-3

Set the expressions equal to each other:
y=y \\ x-3=-3 \ \ \ |+3 \\&#10;x=0 \\ \\&#10;(x,y)=(0,-3)

So, for every nonzero number a the system of equations has one solution.

Create a word problem with the equation x=y^3
ivann1987 [24]

Step-by-step explanation:

The sum of two positive numbers is four and three times the smaller number is one more than the larger. What are the two numbers?

Explanation:

To find such a word problem, we can first note that

1.25

+

2.75

=

4

, which makes a nice easy number to refer to verbally.

In addition, note that

3

⋅

1.25

=

3.75

=

2.75

+

1

, which allows us to formulate the second part of the system.

So we can pose a question like:

The sum of two positive numbers is four and three times the smaller number is one more than the larger. What are the two numbers?

How would you solve it?

Let

x

,

y

represent the smaller and larger numbers respectively.

Then from the question:

{

x

+

y

=

4

3

x

=

y

+

1

Subtracting

y

from both sides of the second equation gives us:

3

x

−

y

=

1

Adding this to the first equation gives us:

4

x

=

5

Then dividing both sides by

4

gives us:

x

=

5

4

=

1.25

Subtracting

x

from both sides of the first equation, we have:

y

=

4

−

x

=

4

−

1.25

=

2.75
