Answer:
4+i
Step-by-step explanation:
A complex number usually took the form a+bi where a and b are real numbers and 'i' represents an imaginary number. For a quadratic equation, the complex roots for the root of a quadratic equation took the form known as complex conjugates. The complex conjugates are formed by changing the sign of the imaginary part.
SO, if a quadratic equation has 4-i as a solution, the other solution must be 4+i.
Set f(x) equal to zero and solve. Use the zero product property.
f(x) = 0
(x-9)(x+12)(x-24) = 0
x-9=0 or x+12=0 or x-24=0
x=9 or x=-12 or x=24
The zeros or roots of the polynomial are: 9, -12, 24
Answer is choice C
Answer:
Step-by-step explanation:
First, subtract 3x. This leaves you with jy=7-3x. Then, divide by j, leaving you with .
Answer: There are no solutions.
Step-by-step explanation: x - 5/3 = x - 3/5
x + -5/3 = x + -3/5
x + -5/3 - x = x + -3/5 - x
-5/3 = -3/5
-5/3 + 5/3 = -3/5 + 5/3
0 = 16/15
Answer:
The horizontal shift is 6 units left (so -6).
Step-by-step explanation:
The horizontal shift is located inside the absolute value bars. While F(x) adds 6 to x, so you may think it's 6 units right, <em>horizontal</em> shifts are backwards as opposed to vertical shifts: we go 6 units left.
