Graph this equation on a graphing calculator, the line crosses the x axis 3 times, those points are at -4 , 2 , and 6
to find on calc, enter equation is y=, then hit 2nd , trace , 2: zero
Same question was posted earlier .... I repeat my answer here ...
Question (2a):
Given that sum of triangle = 180°
∠1 + ∠2 + ∠3 = 180°
∠3 = 180° - ∠1 - ∠2 ---------------- (1)
Given that sum of angles on the adjacent line = 180°
∠3 + ∠4 = 180°
∠4 = 180° - ∠3 ------------------------(2)
Sub (1) into (2)
∠4 = 180° - (180° - ∠1 - ∠2 )
∠4 = 180° - 180° + ∠1 +∠2
∠4 = ∠1 +∠2 (proven)
Question (2b):
∠4 = 52° + 25°
∠4 = 77°
I cant see a list of statements but the graph is a parabola which opens upwards
it factors to (2x + 5)^2 so the root is -2.5 duplicity 2
The vertex of the grapg will just touch the axis at the point (-2.5,0)
The answer would be 3150 square inches
Answer:
14
Step-by-step explanation:
subtract 9 from both sides
and ur answer is 14
Also to check your work do 14+9 to see what u get :)
