We are given the equation 27 x3 + 125 = 0 and is asked in the problem the value of x. In this case, the equation is expressed as 27x3 = -125; x1 = -5/3; x2 =(-15-√-675)/18=(-5-5i√ 3 )/6= -0.8333-1.4434i ; x3 =(-15+√-675)/18=(-5+5i√ 3 )/6= -0.8333+1.4434i
Answer:
(8,-3)
Step-by-step explanation:
I just added 1 to the x value and added 2 to the y value because that was the difference between point A and the midpoint of the segment.
Hope this helps!
Step-by-step explanation:
A. 3x+4/2 = 9.5
3x + 4/2 = 9.5........criss cross
3x+4= 9.5×2
3x = 19-4
3x = 15
x=5 ..........divide both sides by 3
B. 7+ 2x/3= 5.......criss cross
7+2x = 5 × 3
7 + 2x = 15
2x = 15-7
2x = 8......divide both sides by 2
x = 4
