If x represents the mass of 1 ball in kg, then the balance shows ...
... 6x = x + 9 kg
... 5x = 9 kg
Then 6x is ...
... (6/5)·5x = (6/5)·9 kg = 10.8 kg
0.8 kg = 0.8·1000 g = 800 g
so 10.8 kg is ...
... D. 10 kg 800 g
Answer:
The total profit P(x) or the month is
.
Step-by-step explanation:
A company produces x units of a product per month.
The total cost represents by the function C(x).

The total revenue represents by the function R(x).

The profit is the difference between revenue and cost.



Combine like terms.


Therefore, the total profit P(x) or the month is
.
Using the concept of y-intercept, it is found that the response that is not correct is given by:
B) Replace x with -x.
<h3>What is the y-intercept of a function?</h3>
It is the value of the function when x = 0, hence it is the point (0, f(0)).
In this problem, the function is:

The y-intercept is given by:

If we just replace x with -x, we still have the same expression as above, hence the y-intercept does not change and option B is the answer to this question.

Answer: M - 21
Step-by-step explanation:
Since his daughter is 21 years younger than he is (M) all you have to do is take his age and subtract 21 (how many years older he is) to get her age.
At first this might seem difficult because you don't know what M is equal to but in the context of this question you don't need to know M.
If you're ever stuck just give an imaginary number to M such as 50.
If you take 50 and subtract 21 you get 29, this makes sense because his daughter is of course younger than him.
You can also use this tatic to solve problems like x+3=x/2 (or something like that) just to check and make sure that the two equations do equal each other.

Answer:
(11 ft)³
Step-by-step explanation:
Given the shape is a cube, all of its sides are the same.
The formula for the volume of a cube is V = s³ where "s" represents the edge length.
Substitute "s" for 11 ft.
V = s³
V = (11 ft)³
In exponential form, do not solve for the volume. Leave the expression as
(11 ft)³
Without the units, the answer is 11³
