Answer:
20
Step-by-step explanation:
x = price
y = number of keyboard
xy = 540
(x-2)(y+3) = 540
x = 540/y
==> x = 20
==> y = 27
So, do get the answer, you have to find out who got more of the votes, either Carl Green or Maria Lewis. Once you have found out who has more votes, you take the bigger number and subtract the smaller number from it. If you get a negative number, or a number below 0, you have unfortunately have the wrong answer for the problem
Answer:
x = 1, y = 3
Step-by-step explanation:
Use the y and substitute it into the 2nd equation. Solve for x. Then use that answer to solve for y.
The greatest common factor is 2z^3.
In order to find the greatest common factor, always start with the coefficient of the lowest term. Let's see what the factors of 14 are.
Factors of 10: 1, 2, 5, 10
Now we look to see which are also factors of the next highest number.
Factors of 14: 1, 2, 7, 14
Only 1 and 2 are similar factors. Since 2 is also a factor of 70, 2 in the coefficient of our greatest common factor.
Next we look for the term with the least number of z's. 14z^3 is the least number of z's. This means we can take out z^3. Giving us the final answer of 2z^3.
We're given

which immediately tells us that

In other words, swapping the limits of the integral negates its value.
Also,

The integral we want to compute is

which we can do by splitting up the integral at x = 4 and using the known values above. Then the integral we want is
