X + 19 ≥ 8.3 <<< your inequality equation
x ≥ 8.3 - 19
x ≥ -10.7 << your solution
hope this helps, God bless!
Because d actually collects data about what the people want.
Answer:
7
Step-by-step explanation:
The average rate of change of f(x) in the close interval [ a, b ] is

Here [ a, b ] = [2, 5 ]
f(b) = f(5) = 2(5)² - 7(5) = 50 - 35 = 15
f(a) = f(2) = 2(2)² - 7(2) = 8 - 14 = - 6, thus
average rate of change =
=
= 7
