Answer:
2
Step-by-step explanation:
A commutative function means that when you insert one function in space of x in the other function, they will equal x. The equation is f(g(x)) = g(f(x)) = x
So, 2(
) - 1 = 
If you multiply both sides by <em>a</em>, you get 2<em>a</em>(
) - a = (2x-1)+1
Simplify it 2<em>a</em>(
) - <em>a</em> = 2x
Add <em>a</em> to both sides 2<em>a</em>(
) = 2x +<em>a</em>
The two <em>a</em>s on the left cancel out 2(x+1)=2x+<em>a</em>
Distribute the 2 2x+2=2x+<em>a</em>
Then subtract 2x from both sides 2 = <em>a</em>
Therefore, <em>a</em> = 2
Hope this helps!
Answer:
C = 2000 + 25 * X
$ 7000
Step-by-step explanation:
We have that the value of the total costs is equal to the fixed costs plus the variable costs.
As fixed costs we have $ 2000 and variable cost we have $ 25 for each unit, that is, the equation for total costs would be:
Let x be the number of toys, then:
C = 2000 + 25 * X
If there are 200 toys, the cost would be:
Replace x with 200:
C = 2000 + 25 * 200
C = 7000
In other words, the cost of producing 200 toys would be $ 7000.
hello :)
so here i am assuming that 66m^2 is the area and the height is 6.3 (sorry, but the way you wrote it is a bit funny, its all good tho)
so to calculate area it is hieght multipled by width
so you have to divide 66 by 6.3, which gives you this very long number : 10.4761904762
i would personally round it to either just 10 or 10.5
so you would want to write the answer as ≈10.5
hope that helped!
i would appreciate it if you voted me as brainliest :)
Answer:
-8
Step-by-step explanation:
you need to rewrite it in y=mx+b form where b-is the y-intercept
y-4= -3(x+4)
distribute
y-4 = -3x-12
isolate y
y= -3x-8
compare this with the y=mx+b so y-intercept is -8
