An identity is the same on both sides of the equals sign
C: 10p + 6 -p=12p-3(p-2)
9p +6 = 12p -3p +6
9p +6 = 9p +6
Answer:
- no real solutions
- 2 complex solutions
Step-by-step explanation:
The equation can be rearranged to vertex form:
x^2 -4x = -5 . . . . . . . . . subtract 4x
x^2 -4x +4 = -5 +4 . . . . add 4
(x -2)^2 = -1 . . . . . . . . . show the left side as a square
x -2 = ±√-1 = ±i . . . . . . take the square root; the right side is imaginary
x = 2 ± i . . . . . . . . . . . . . add 2. These are the complex solutions.

<em>Comment on the question</em>
Every 2nd degree polynomial equation has two solutions. They may be real, complex, or (real and) identical. That is, there may be 0, 1, or 2 real solutions. This equation has 0 real solutions, because they are both complex.
Answer:
12
Step-by-step explanation:
The 2 lines are equal in length. Therefore:-
ST = 21 - 9 = 12
Answer:
A = P(1 + r/100)^n
A = 1000 x (1.08)^n
Step-by-step explanation:
n is the number of years, p is the principal, A is the amount.
The lamp is appreciating (increasing in value) so every year, its value is 1.08 times its value the year before.
Use the first equation to be more general, use the second equation if there isn't anything below asking you to input numbers into the equation.
Probably just use the first one.
