Answer:
A
Step-by-step explanation:
Here, we want to select the option that best describes the commission earned;
In the question, we are told that the commission is a certain percentage variable on the amount of her sales;
Thus , mathematically to get the percentage commission, we simply need to have;
p(x) of f(x)
This simply refer to placing f(x) into p(x) which can be rewritten as ;
p o f(x)
The closest answer to this is the first option A
Maggie reads 2/3 of a book per week.
From the question,
We are to determine the number of books Maggie reads per week.
Let x represent the number of books she reads per week.
From the given information,
Maggie reads 1/3 of a book every 3/4 of a week
If Maggie reads 1/3 of a book every 3/4 of a week
Then,
She will read x of a book in 1 week
x =
x =
x =
x =
x =
Hence, Maggie reads 2/3 of a book per week.

Answer: B) y-4=6(x-1)
Substitute the point into each equation
A: y-4=6(x+1)
4-4=6(1+1)
4-4=6+6
0=12
This is false so it is not the answer
B: y-4=6(x-1)
4-4=6(1-1)
4-4=6-6
0=0
This is true so this is the answer, but I will continue solving just to check
C: y+4=6(x-1)
4+4=6(1-1)
4+4=6-6
8=0
This is false so it is not the answer
D: y+4=6(x+1)
4+4=6(1+1)
4+4=6+6
8=12
This is not true so it is not the answer
Your answer becomes b, the only true equation! Hope this helps comment below for more questions :)
Answer:
Step-by-step explanation:
The given system is:
Since I prefer to use smaller numbers I'm going to divide both sides of the first equation by 3 and both sides of the equation equation by 6.
This gives me the system:
We could solve the first equation for and replace the second with that.
Let's do that.
Subtract on both sides:
So we are replacing the second in the second equation with which gives us:
Now recall the first equation we arranged so that was the subject. I'm referring to .
We can now find given that using the equation .
Let's do that.
with :
So the solution is (8,-1).
We can check this point by plugging it into both equations.
If both equations render true for that point, then we have verify the solution.
Let's try it.
with :
is a true equation so the "solution" looks promising still.
with :
is also true so the solution has been verified since both equations render true for that point.
