<u>Algebra I</u>
- Terms/Coefficients/Degrees
Step-by-step explanation:
<u>Step 1: Define</u>
5(2x - 1) - 2(3x + 2)
<u>Step 2: Solve for </u><em><u>x</u></em>
- Distribute: 10x - 5 - 6x - 4
- Combine like terms (x): 4x - 5 - 4
- Combine like terms (Z): 4x - 9
We are given with two conditions and we label each positve number as x and y. The sum of the 2 numbers is x + y equal to S. The product is maximum.
The product is xy. To find the maximum
P = xy = x (S- x) = Sx - x2
dP = S - 2x = 0
hence x = S/2
y then is equal to S/2 also.
Answer:
2log₅(x) - 2log₅(4)
Explanation:
Note the following rules before we begin:
log(a) - log(b) = log(a/b)
2log(a) = log(a²)
Now, for the given, we will work backwards as follows:
log₅(x/4)² = 2 [ log₅(x) - log₅(4)]
= 2log₅(x) - 2log₅(4)
Hope this helps :)
The polynomial x3+8 is equal to (x+2)(x2-2x+4)
