-1 to any odd power has value -1
To solve, remove the 7 from 7x. Since the 7 and x are attached by multiplying, divide:
7x / 7 = t / 7
x = t/7

If you start with (x - 4)(x - 5) (x - 7) (x - 9) and multiply by x² + x (which is x(x + 1) )
and multiply by 1 - x
The roots will be the values that make the original factors zero; specifically, 4, 5, 7, 9, 0, -1, and 1.
If you have a common fraction such as 3/4, enter it that way; that is 3 / 4
1 = (x - 4)²
Find the square root of both sides, use the symbol ± on either side:
√1 = ±1 √(x - 4)² = x - 4
±1 = x - 4
Add 4 to both sides: 4 ± 1 = x ---> x = 4 + 1 = 5 x = 4 - 1 = 3
-y² + 9 = 9 - y²
This is the difference of two squares with the form: a² - b² = 9(a - b)(a + b)
So: 9 - y² becomes (3 - y)(3 + y)
How are taxes calculated in New York? What is the percentage rate (or rates)? Can federal taxes be subtracted before state taxes are calculated? Please give more information.
"25% of" means "0.25 times" so the problem reduces to: .25 X 247 =
