Answer:

Step-by-step explanation:

<em>Replace it with y</em>

<em>Exchange the values of x and y</em>

<em>Solve for y</em>

<em>Subtracting 1 from both sides</em>

<em>Dividing both sides by 2</em>

<em>Replace it by </em>
So,

F(x + 1) = (5/2)*f(x)
f(x + 1) = 2.5*f(x), f(1) = 3.2
f(2) = 2.5f(1) = 2.5*3.2 = 8
<span>f(3) = 2.5f(2) = 2.5*8 = 20
</span>
f(4) = 2.5f(3) = 2.5*20 = 50
<span>f(5) = 2.5f(4) = 2.5*50 = 125</span>
8) 5 + 4 + 2 = 11
Since there are 5 guavas, the correct answer is B. 5/11
9) 3 + 4 = 7
Since there are 4 blue papers, the correct answer is A. 4/7
10) Count all of the numbers and add them. There are 4 twos, 2 fives, and 1 three:
4 + 2 + 1 = 7
Since there are 4 twos, the correct answer is C. 4/7
The first step is to square root both sides to get the exponent out. that actually is the only step :)
