Answer:
16
Step-by-step explanation:
plugin -7 for where x is
f(-7)= (-3)(-7)-5
=21-5 is 16
Answer:
6²
Step-by-step explanation:
Using the rule of exponents
⇔ 
, then
= 
= 6²
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
