The answer would be 1,600 because it’s a fraction
N=9
Use the distributive property
Y = (x + 4)(x - 2)
The x-intercepts:
0 = x + 4
0 = x - 2
x = -4
x = 2
The vertex:
y = (x + 4)(x - 2)
y = x^2 + 2x - 8
x = -b/2a
If ax^2 + bx + c, then:
a = 1
b = 2
c - 8
x -2/2(1)
x = -1
y = (-1)^2 + 2(-1) - 8
y = -9
The vertex is (-1, -9)
The x-intercepts are -4 and 2
"Lines s and t have slopes that are opposite reciprocals." In your shoes I'd write that as "<span>Lines s and t have slopes that are negative reciprocals of one another."</span>
