Answer:
X=2
Step-by-step explanation:
When x is 2, y=3 for both equations
Well take 500 and subtract the 236 then divide the rest by two and the answer should be 132
Answer: The vertex of the parabola (quadratic function) is (-2,-4)
Fourth option: (-2,-4)
Solution:
y=x^2+4x
y=ax^2+bx+c; a=1, b=4, c=0
Vertex: V=(h,k)
h=-b/(2a)
h=-4/(2(1))
h=-4/2
h=-2
y=x^2+4x
k=y=h^2+4h
k=(-2)^2+4(-2)
k=4-8
k=-4
Vertex: V=(h,k)
Vertex: V=( -2, -4)
Answer:
-10 because you do parenthesis first
Plug into y-y1=m(x-x1)
y+4=4(x-4)
