Just add and subtract the numbers with the same letters
Answer:
- 2
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is

Here [ a, b ] = [ - 2, - 1 ] , then
f(b) = (f(- 1) = 5 ← corresponding value of y (- 1, 5 )
f(a) = f(- 2) = 7 ← corresponding value of y (- 2, 7 ) , thus
average rate of change =
=
= - 2

Combining the above inequalities, we get :


A vertical angle includes each of the pairs of opposite angles made by two intersecting lines, so ∠EKF and ∠HKI is the answer.
Answer:
it's less than
Step-by-step explanation:
12/8 simplified is 3/2
11/6 cannot be further simplified
3/2<11/6
