Answer:
52%
Step-by-step explanation:
13/25
13 ÷ 25
0.52
0.52 × 100/100
0.52 × 100%
(0.52 × 100)%
52%
The vertex is when x=-b/2a, which is also the line of symmetry.
in this case, b=6, a=3, so x=-6/6=-1
when x=-1. y=3-6-1=-4
another way to do it is to write the equation into vertex form by making a square:
3x²+6x-1
3(x²+2x-1/3)
3(x²+2x+1-1-1/3))
3(x²+2x+1-4/3))
notice the bold part makes a square:
3(x+1)²-4
Either way,
the vertex is (-1, -4)
the axis of symmetry is x=-1
the coefficient of x² is 3, a positive number, so this parabola opens upward. the function has a minimum value of y=-4
the range is all real number larger than -4
11/30 - 6/30 - 5/30 = 0
The answer is 0
Point slope: y - y1 = m(x - x1)
Plug in the points
Answer: y - 5 = 1/3(x + 2)
Answer:
2x - 5
Step-by-step explanation:
2x + 4 - 9
the 2x gonna stay
so you take 4 - 9 = -5
so the answers gonna be 2x - 5
bc the 5 is negative so you gonna subtract
I hope you understand my english...
