The vertex of a quadratic occurs when the velocity, dy/dx=0.
dy/dx=2x+8, so dy/dx=0 only when:
2x+8=0
2x=-8
x=-4, now you find the y coordinate which is:
y(-4)=(-4)^2+8(-4)+12
y(-4)=16-32+12
y(-4)=-4 so the vertex is at the point:
(-4,-4)
5/8 bc 3+2 is 5 and the denominator stays the same:)
Answer:
25 to 1
Step-by-step explanation:
5a/2b = 1/10
cross-multiply:
50a = 2b
simplify to get 25 : 1
