Answer:
-$53.74
Step-by-step explanation:
96.26 - 150.00 = -53.74
Step-by-step explanation:
0.25 = one quarter - 2/8
3/8 is spent on food
so this leaves 3/8 for savings
therefore we know that $18.27 is 3/8 of her total allowance
so
18.27 ÷ 3 = 6.09
6.09 × 8 = 48.72
thus her total allowance must have been $48.72
Equation B is linear. A linear equation will not contain exponents.
Since f(x) is a polynomial with 3rd degree, then it will have 3 roots (zeroes)
One of them is real and the other two are complex conjugate roots
Since the real root is 4, then
x = 4
Since the complex root is (1 - i), then
The other root will be the conjugate of it (1 + i)
x = (1 - i)
x = (1 + i)
To find f(x) we will multiply the three factors of it
We can get the factors from the zeroes

Subtract 4 from both sides

The first factor is (x - 4)

The second factor is (x - 1 + i)
The third factor is (x - 1 - i)

We will multiply them to find f(x)

Multiply it by (x - 4)

The answer is
