Hello,
5i or -5i since there would be at least 4 roots
Answer B and E
Here you should use the equation y - y1 = m(x - x1), where (x1, y1) are a point and m is the slope:
y - 1 = -3(x - 2)
I'm not sure if perhaps there's an error in the question or the re-typing but none of the answers stated above match the solution.
Answer:
X = 13/3
Step-by-step explanation:
24x - 6 = 9x + 38+21
24x - 9x= 38 + 21 + 6
15x = 65
X = 65/15 = 13/3
X = 13/3
(x-7)/(7-x) if you factor out -1 from the numerator you get:
-(7-x)/(7-x) which is equal to:
-1
Answer:
2 (real) solutions.
Step-by-step explanation:
A quadratic always has two solutions, whether they are real or complex.
Sometimes the solution is complex, involving complex numbers (2 complex), sometimes they are real and distinct (2 real), and sometimes they are real and coincident (still two real, but they are the same).
In the case of
x^2+3x = 3, or
x² + 3x -3 = 0
we apply the quadratic formula to get
x = (-3 +/- sqrt(3^2+4(1)(3))/2
to give the two solutions
{(sqrt(21)-3)/2, -(sqrt(21)+3)/2,}
both of which are real.
