Answer:
the answer is 32 to the 3rd power
Step-by-step explanation:
Answer:
The value of k is 11.
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
2=(k-3)/(5-1)
2=(k-3)/4
2*4=k-3
8=k-3
k=8+3
k=11
Descares Theorem says that the number of roots of a polynomial is equal to its highest exponent, and the roots could be real and/or imaginary (complex).
However is their is one complex root (a + i.b), it's conjugate is also
a root (a-i.b).
In the equation x⁴ - 4x³ - 2x² + 12x + 9 = 0, we have already 3 roots, then the 4rth cannot be a complex one since we don't have a fifth for its conjugate.
"Increased by" means to multiply.
First, change the percentage to a number.
% ⇒ # : %/100
120(%) (120 ÷ 100) = 1.2
Now, you multiply.
5x × 1.2 = 6x
So, your answer is 6x.
