Answer:
y=0.5(x+6)(x+5)
Step-by-step explanation:
Since the parabola goes upwards as it expands from the vertex, the "a" value is definitely positive so the answer must be either the top-left or bottom-right. Next, use the roots to find the final answer. The roots are on the left side of the y-axis which indicates that they are negative. Now you know that the answer is the bottom-right answer because if both roots are negative, then the expressions must include addition to create 0 which is the y-value at the bases.
B. =
.60=.6
its just like 60 and 060 the 0 is useless
-4/5=2b
since b is alrteady in the subject of the equation simply divide both side of the equation by the coefficient of b
:. (-4/5)/2= 2b/2
-4/10=b
:. b=-2/10 or -0.4
