Answer:
X-Intercept = (1,0) and (3, 0)
Y-Intercept = (0, 6)
Vertex = (2, -2)
Maximum or Minimum = It is minimum, the vertex is the lowest number.
Axis of Symmetry = x = 2
Zeros = (1, 0) and (3, 0)
Domain = all real numbers
Range = y ≥ -2

2:1 should be your answer.
Answer:
x = 19
Step-by-step explanation:
Solve for x:
3 x + 43 = 100
Subtract 43 from both sides:
3 x + (43 - 43) = 100 - 43
43 - 43 = 0:
3 x = 100 - 43
100 - 43 = 57:
3 x = 57
Divide both sides of 3 x = 57 by 3:
(3 x)/3 = 57/3
3/3 = 1:
x = 57/3
The gcd of 57 and 3 is 3, so 57/3 = (3×19)/(3×1) = 3/3×19 = 19:
Answer: x = 19
