This is a parabola, first, locate the line of symmetry.
the line of symmetry is x=-b/2a
in this case, b=-2, a=-1, so the line of symmetry is x=-1
when x=-1, f(x)=-(-1)²-2(-1)-3=-2
locate the point (-1,-2) on the grid. this point is the vertex.
get two pairs of points with x=-1 as the symmetry line:
(0, -3) and (-2, -3); (1,-6) and (-3,-6)
connect these five points into a parabola, stick out at the ends because it will extend forever downward.

!!!!20 POINTS!!! Find the value of A/B/C if a=3, b=4, c= 1/8

svetlana [45]

So, A divided by B divided by C? That would mean 3 divided by 4 divided by 1/8, correct? The answer for that would be 6, I believe. Hope that helps!

*NEED HELP!*

Answer and Step-by-step explanation:

$Hello!~$

$Let's~answer~your~question!$

$So,~for~this~equation,~we~need~to~use$ $~the~distributive~property~of$ $~multiplication.~but,before~we~start~to~solve$ $this~equation,~let's~get~to~know~what$

$distributive ~property ~of~multiplication~means!$

Distributive property of multiplication :

$Distributive~property~of~multiplication~states~that$ $when~a~~number~is~multiplied$

$by~the ~sum ~of~ two~ numbers,$ $the~ first~ number ~can~ be ~distributed ~to$ $both ~of~those$ $numbers~and~multiplied~by~each~of~them$ $separately.$

→ $a*(b+c)=a*b*+~a*c$

Now, that we know what it means let's apply it in our equation:

 $(2*x)+(2*7)=36$ 

Now, we simplify:

 $2x+14=36$ 

Divide both sides by 2 in the equation:

 $\frac{2x+14}{2} =\frac{36}{2}$ 

Simplify :

 $x+7=18$ 

Thus, the first correct step is option B,

 $then~comes,~option~"A"~then,~option~"F"~as~shown~above$ $The~remaining~options~are~not~enough~information~to~solve~the~given$ $equation:(x + 7) = 36.$
