Y=-2x+2
y=x2-2x+4
is the value of x such that when you plug it into both equations, they both produce the same value of y, or the value of x such that
-2x+2=x2-2x+4
solving this equation----------> x2=-2, taking square root of both sides gives x= ±√2i, or the system has no real solutions but has 2 complex solutions. If you graph both functions in the xy-plane, where x, y are real numbers, you' ll see they do not intersect, which implies there is no real number solutions.
We want to verify that x² + x - 12 = (x - 3)(x + 4)
We can prove this by factoring the left side and showing that it is equal to the Right side.
We should find factors of -12 that sum to +1.
-12 = 1 x -12 Sum = 1 - 12 = -11 No
-12 = 2 x -6 Sum = 2 - 6 = -4 No
-12 = 3 x -4 Sum = 3 - 4 = -1 No
-12 = 4 x -3 Sum = 4 - 3 = 1 Yes
Therefore
x² + x - 12 = (x - 3)(x + 4) which is equal to the Right side.
Latisha is correct because
4(-3) = -12, and
-3 + 4 = 1
Answer: Latisha
6m mabey help=asap yea but l may be wrong sov6ea
1) montly rate, r = 5% / 12 = 0.416% = 0.00416
2) capital, C = $ 450 = present value
3) time = 11 years => number of periods = 11 * 12 = 132
4) Formula: FV = C * (1 + r) ^ (number of periods)
5) Calculation: FV = $450 * ( 1 + 0.00416)^(132) = $ 779.07
Answer: $ 779.07
