Answer:
sum of two even numbers will always be even. conjecture just means to make a generalization based on patterns
The slope of AC is -0.4
Proof:
In triangles ABC and DBE,
∠DBE is common to both triangles.
AB = 2DB (D is the midpoint of the interval AB)
Also, BC = 2BE (E is the midpoint of the interval BC)
Thus triangles ABC and DBE are similar in the ratio 2:1
Since, they are similar, ∠BDE must equal ∠BAC (corresponding angles in similar triangles)
If ∠BDE = ∠BAC, DE must be parallel to AC (corresponding angles are equal along parallel lines)
Thus, the slope of AC = the slope of DE
Thus, the slope of AC is -0.4
(-10,-4)
m=-12
y+4=-12(x+10)
y+4=-12x-120
y=-12x-124
Answer:
Step-by-step explanation:
Use implicit differentiation:
Remember to treat "y" as a constant in implicit differentiation and include dy/dx.
