Answer:

-1

Step-by-step explanation:

The formula for D/4 is b'^2-ac (where b' = 4/2=2, a=1, c=5). When we use the special discriminant (D/4) we get D/4 = (2)^2-1*5 = 4-5=-1.

Hope this helps!

In the given figure, BAC = 90° and ABC = 45°. Prove that: AB = AC.

Amiraneli [1.4K]

Answer:

<h2>By angle sum property:</h2>

BAC+ABC+BCA=180°

90°+45°+x=180°

135°+x=180°

x=45°=BCA

<h2>since BCA=ABC=<u> </u>45° each </h2><h2>therefore,</h2>

$AB=AC \\ (isosceles \: triangle \: \\ theorem)$

What is the value of the function when x = 1?

sattari [20]

Just look at the x axis (horizontal) and see where x=1 or go 1 unit from the origin (0,0), then go up untill you hit a point that coresponds witha y value which looks to be 2 so coresponding y for x=1 is y=2

if we are given point (1,2) then
(x,y)
x=1
y=2
that is the solution already
