Answer:
The inverse of the function h(x) is 
.
Step-by-step explanation:
The given function is
Replace h(x) by y.
Interchange x and y.
Subtract 4 from both sides to isolate variable y,
Multiply both sides by 2.
Divide both sides by 5.
Replace y by h⁻¹(x).
Therefore the inverse of the function h(x) is .
Given:
22
gallons of 16% ammonia
24%
ammonia
Find:
Number
of gallons of water to remove
Solution:
Let
n = number of gallons needed to obtain 24% ammonia
22
gallons (0.16) = n (.24)
<span>N = 14.67 gallons of water</span>

Answer:
8
Step-by-step explanation:
Like term is having the same variables and powers
each bolded below has the variable z other than 8 (second one)
8z, 8, 4z, -8z
<span>Every integer is a rational number, since each integer n can be written in the form n/1. For example 5 = 5/1 and thus 5 is a rational number. i hope this helps you</span>
