Answer:
ax^2 + bx + c
Step-by-step explanation:
The standard form of an equation of a parabola is ax^2 + bx + c
a and b are coefficients and b is a constant
A parabola opening up has a positive a value while a parabola opening down has a negative a value
Answer:
y=2
Step-by-step explanation:
The Y=0 Line is the X-axis, where there is no altitude. Adding 2 to zero shift the line up to pass through the point (0,2).
We know the perimeter is the sum of all sides. So lenght+length+width+width = 2length+2width.
Let's call the width x. If the length is 4m longer, then it's x+4.
We know the perimeter, so we can make an equation:
56=2x+2(x+4)
And solve from there:
56=2x+2x+8
56=4x+8
48=4x
48/4=x
x=12
The width, which is x, is 12 m. And the length, x+4, is 16 m.
You can check this is correct by calculating the perimeter using those values: 12+12+16+16=56.
2x-y+2=0
slope=y-y/x-x
6-(-6)/2-(-4)=2
eq=Y-y/X-x
y-6/x-2=2
2x-4=y-6
2x-y+2=0
