Answer:
-80
Step-by-step explanation:
The average rate of change is
a.r.c = f(4) - f(1)
--------------
4-1
f(4) = 244 and f(1) = 484
a.r.c = 244 - 484
--------------
3
= -240/3
=-80
Answer:
b= 29/11
Step-by-step explanation:
2b+8−5b+3=−13+8b−5
Step 1: Simplify both sides of the equation.
2b+8−5b+3=−13+8b−5
2b+8+−5b+3=−13+8b+−5
(2b+−5b)+(8+3)=(8b)+(−13+−5)(Combine Like Terms)
−3b+11=8b+−18
−3b+11=8b−18
Step 2: Subtract 8b from both sides.
−3b+11−8b=8b−18−8b
−11b+11=−18
Step 3: Subtract 11 from both sides.
−11b+11−11=−18−11
−11b=−29
Step 4: Divide both sides by -11.
−11b/−11 = −29/−11
b= 29/11

Answer:
Step-by-step explanation:
m∠ABD=½m∠ABC
So, BD is the angle bisector of ∠ABC.
∠ABD = ∠DBC
So, if we know ∠ABC, then we can find ∠ABD & ∠DBC
Eg: If ∠ABC = 50, then ∠ABD = 50/2 = 25
As ∠DBC = ∠ABD
∠DBC = 25
