The complete factored form of the quadratic expression is (x-8y)(x-8y)
<h3>Factorizing quadratic expression</h3>
Quadratic expressions are expressions that has a leading degree of 2
Given the expression
x^2 – 16xy + 64y^2
Factorize
x^2 - 8xy - 8xy + 64y^2
Group
(x^2 - 8xy) - (8xy + 64y^2)
x(x-8y) - 8y(x - 8y)
Since (x-8y) is common, hence;
x^2 - 8xy - 8xy + 64y^2 = (x-8y)(x-8y)
The complete factored form of the quadratic expression is (x-8y)(x-8y)

What is the "straight line rate?" To obtain this, subtract the $600 residual value from the "new cost," $18,000. Result: $17,400.
The straight line rate would then be $17,400/5, or $3,480; twice that would be $6,960.
After one year, the book value at the end of year 1 would be $18,000-$6,960 = $11,040.
Follow a similar process to find the book value at the end of year 2. Twice the original depreciation at this point would be $6,960, as before. Subtracting this from $11,040 results in a book value at the end of year 2 of $11,040-$6,960= $4,080.
There may be other interpretations dictating what to do here. I'd suggest you look up "declining balance method" and compare it to what we have done here.
Answer:
b graph A, set B
Step-by-step explanation:
The 3rd equation, as if you solve for x as shown, you will end up with equation x=8.
Answer:
1 month
Step-by-step explanation:
249 is the amount she spends for buying the kitten, (299-50=249) which she only has to pay once.
20 is the amount she has to spend every month, the rate of change.
The problem can be modeled with the general equation:
y = 20x + 249
In this equation, x the the time in months and y is the amount of money spent.
Substitute 250 for y.
y = 20x + 249
250 = 20x + 249 <= isolate x to get the number of months
1 = 20x
x = 1/20
Carol will only spent money every month, not for 1/20 of a month.
It will only take Carol 1 month to spent $250.
Check answer:
Substitute x for 1
y = 20x + 249
y = 20(1) + 249
y = 269
269 is more than 250 already.
