4b + 22 = 5 (b + 4) - 1 (remove the parantheses)
4b + 22 = 5b + 20 - 1 (calculate)
4b + 22 = 5b + 19 (move the terms)
4b - 5b = 19 - 22 (collect like terms and calculate)
-b = -3 (change the signs)
<em>b = 3</em>
Answer:
h(7) = 29
h'(7) = 44
Step-by-step explanation:
If 
, to find h(7) we can substitute the values of f(7) and g(7) and we get:
To find the derivative, we know that the derivative of a sum of functions equals the sum of the derivatives of those functions.
This would mean that 
, we can substitute the values for f'(7) and g'(7)
Hi there!
You would use open intervals.
In the given inequality, the "<" sign is used, which means "greater than".
Open intervals would be used unless the inequality uses "≤" or "≥", which
mean "equal to or greater/less than". Closed brackets would be used in this
instance.
