Answer:

Step-by-step explanation:
Given


Required
Determine the average rate of change
Average rate is calculated as thus;

<em>In this case; b = 12 and a = 6</em>
Calculating f(12)



Calculating f(6)



Substitute 12 for b and 6 for a in 

Substitute values for f(6) and f(12)



Answer: A
Step-by-step explanation: because you cant simplify 3 or 6 anymore but the rest you can 9 can be simplified to 3 and 3
Answer:
inches
Step-by-step explanation:
Following what the problem mentions:
"eric is 70 inches tall"

"pablo is as half as tall as eric"


and "annette is 5.25 inches taller than pablo"


Annette is 40.25 inches tall
Here's one way to do it.
AB ≅ AC . . . . . . . . . . given
∠BAY ≅ ∠CAY . . . . given
AY ≅ AY . . . . . . . . . . reflexive property
ΔBAY ≅ ΔCAY . . . .. SAS congruence
XY ≅ XY . . . . . . . . . . reflexive property
∠AYB ≅ ∠AYC . . . . CPCTC
BY ≅ CY . . . . . . . . . . CPCTC
ΔXYB ≅ ΔXYC . . . .. SAS congruence
Therefore ...
∠XCY ≅ ∠XBY . . . . CPCTC
Your answer is 7.
I subtracted 5 from 12 to find the missing number for KL that is 7.
Therefore, your answer is 7
