Answer:
3/2
Step-by-step explanation:
There are a lot of fractions that equal 1.5, but if you're asking for the most simplified fraction, 3/2 is the answer.
The standard equation is y=ax^2+bx+k and the vertex way is y=a(x-h)(x-h)+x
so the coordinate for x is -b/2a, for your problem a=-4 b=-16 so the coordinate for x is -(-16)/(2*(-4))=-2. Now you have to replace x=-2 in your equation y=-4(-2)^2-16(-2)-11= 5.
The vertex is (-2, 5)

Answer:
6.∠ADB = ∠BDC reason :(CPCTC)
7.BD bisects ∠ADC reason :(From statement 6)
Hope it helps you........
Answer:
(-2,1)
Step-by-step explanation:
add 3 to x,(-5 + 3 = -2) and subtract 2 from y,(3 - 2 = 1)
