Answer: B. 130% increase
Step-by-step explanation:
Given function : 
If x represents the number of years, we have to determine the two values of y in consecutive terms to determine if the value of y increases or decreases after a year.
This function is equivalent to the exponential growth function
, where A=0.35 and (1+r)=2.3, [A= initial amount , r=annual percent increase]
Thus,

Hence, the annual percent increase is 130%.
Y = -3/8x - 7....add 3/8x from both sides
3/8x + y = -7 ...multiply both sides by 8
3x + 8y = - 56 <==
Answer:
x^2 + 2x + 2.
Step-by-step explanation:
Write it in factor from:
(x - (-1 + i))(x - (-1 - i)) = 0
(x + 1 - i)(x + 1 + i) = 0
= x^2 + x + ix + x + 1 + i - ix - i -i^2
= x^2 + 2x + 1 + 1
= x^2 + 2x + 2.
The recursive definition for the amount of the blood pressure medicine in hareem bloodstream after n hours would be 
Hence, option B is correct.
<h3>What is the recursive rule?</h3>
A rule is defined such that its definition includes itself.
Example:
F(x) = F(x-1) + c
is one such recursive rule.
Hareem takes medicine to control his blood pressure.
he takes a 25 mg pill in the morning.
Suppose that 60% of the medicine is processed by hareem's body by the time he takes a second 25 mg pill in the evening.
So, the recursive definition for the amount of the blood pressure medicine in hareem bloodstream after n hours would be;

Hence, option B is correct.

The rational number is equivalent to 0.36 is 9/25
<h3>How to determine the equivalent rational number?</h3>
From the question, we have the following decimal number that can be used in our computation:
Decimal number = 0.36
To start with, we need to express the decimal number as a fraction
This is represented as follows:
So, we have the following representation
Decimal number = 36/100
Change the label of the above representation to rational number
Rational number = 36/100
Simplify the rational number (divide the numerator and the denominator by 2)
Rational number = 18/50
Simplify the rational number (divide the numerator and the denominator by 2)
Rational number = 9/25
Hence, the equivalent rational number is 9/25
